“How will you say from now on to Pharaoh, each one of you about himself, I am a son of the wise? Since he will fail because of your counsel, how will you boast before him to say, We are sons of the wise, O you who are a son of the kings of old.”

“The burden of Egypt. In this part he threatens the destruction of the Egyptians, following out its manner and order; and it is divided into three parts: first, the preparation of the punishment is described; in the second, the destruction itself, at "and I will deliver Egypt"; in the third, the resulting benefit, at "in that day there shall be five cities." Now the preparation of the punishment is described as to four things. First, as to the disposition of the enemies: "he shall ascend" — by inspiring — "upon a cloud," from which comes the storm; "light," on account of agility and readiness: Ps. 96: "cloud and darkness are round about him." Second, as to the stupefaction of the ruling gods. "And they shall be moved": because they were broken by the Assyrians; or because they were not able to give an answer; or because they did not even appear to man on that same day. Ez. 6: "they shall be broken," etc. "The heart of Egypt," that is, the king and the princes, from whom all the vigor of Egypt comes. Above, 1: "every head is languishing, and every heart sad." Third, as to the dissension of those resisting: as to outward engagement, "to clash"; as to strangers, "the Egyptians"; as to kinsmen, "man shall fight"; as to acquaintances and friends, "and man against his friend"; as to different peoples, "city." He sets down the diversity of wills: "it shall be broken up," that is, divided, "the spirit," that is, the will, "in its bowels," that is, in the inhabitants of the land. Matt. 12: "every kingdom divided against itself shall be made desolate." Fourth, as to the error of men taking counsel: "and the counsel." Job 5: "he catches the wise in their own craftiness, and scatters the counsel of the wicked" — and of the demons: "and they shall inquire" — in vain. Above, 8: "and when they shall say to you: seek unto pythons, and unto wizards who mutter in their enchantments," etc. Note, concerning that word "upon a cloud," that there is a manifold cloud. The first is of the flesh assumed. Job 38: "Where were you when I made a cloud its garment, and wrapped it in darkness as in swaddling clothes of infancy?" The second is of the virginal womb. 3 Kings 18: "Behold a little cloud arose out of the sea." The third is of the devout mind. Ps. 67: "His magnificence and his power are in the clouds." The fourth is of the seat of judgment. Ps. 96: "Cloud and darkness are round about him; justice and judgment are the preparation of his seat." Also note that from the first cloud proceeds the sacramental or sanctifying rain. John 19: "from the side (of the Lord) immediately came out blood and water." From the second proceeds the food of consolation. Wis. 19: "the cloud overshadowed the camp, and out of the water that was before, dry land appeared." And below: "seeing your wonders and marvels: for like horses they fed on the food." Above, 18: "like a cloud of dew." From the third proceeds the flashing of preaching. Job 37: "the clouds long for the grain, the clouds scatter their light." From the fourth proceeds the storm of damnation. (Jer. 4): "behold as a cloud"; Ps. 67: "his power is in the clouds." Also note, concerning that word "a light cloud," that the first is called light on account of the dignity of its eminence. Daniel 7: "behold, one like the son of man came in the clouds." The second is called light on account of the purity of virginity. Apoc. 14: "and behold a white cloud, and upon the cloud one sitting like to the son of man." The third is called light on account of the swiftness of obedience. Below, 60: "who are these that fly as clouds?" The fourth is called light on account of the ease of its execution. Ecclus. 43: "in his greatness he set the clouds, and the stones of hail were broken." "And I will deliver Egypt." Here he pursues the destruction itself: first, as to the servitude of the people; second, as to the desolation of the land, "and it shall be dried up"; third, as to the stupefaction of the wise men, "the princes are fools." "Of masters" — of the Assyrians, the Chaldeans, the Romans. Deut. 28: "you shall serve your enemy." Now he designates the destruction of the land through the dryness of the waters, in which Egypt is adorned and rich: either because the wrath of God brought it about beforehand that the waters should dry up, and the animals die; or he speaks hyperbolically, as if to say: the tribulation will be so great that it will seem even to dry up the waters. He sets down, therefore, three things. First, the manner of the drought: "it shall be dried up," that is, diminished, "the river" — the Nile — "the streams," the other rivers. Ezechiel 30: "I will make the channels of the rivers dry." Second, he sets down the sign of the drought: "the reed and the bulrush," which are nourished in the waters. Below, 35: "the greenness of the reed and the bulrush shall spring up." Third, he sets down the harm of the drought: "it shall be made bare" — first, of agriculture, "from the fountain," that is, from the beginning; or this refers to the end. Ps. 106: "he turned rivers into a desert, and the outgoings of waters into thirst." Second, of the fishermen: "the fishermen shall mourn." Ezech. 29: "I will cast you into the desert, and all the fish of your river." Third, of the various craftsmen: "they shall be confounded who work in flax," which grows in moist places. "Withering," that is, drying up; "ponds," fish-ponds. "The princes are fools." Here he sets down the stupefaction of men: first, as to error in counsels; second, as to fear in wars, at "in that day." Concerning the first, three things. First he mocks the folly of the wise as to deliberation: "the princes are fools" — that is, the philosophers — "of Tanis," where study flourished: Jer. 51: "every man has become foolish"; as to the promulgation of counsel: "the wise"; as to their own self-commendation: "how will you say to Pharaoh?" That is, how will you be able to say, when he will think that you have counseled badly, this thing which each one of you was accustomed to say for his own commendation, so that his counsel might be believed: "I am the son of the wise" — as if to say, I possess wisdom by inheritance; or "a disciple of the kings" — who of old were philosophers. Job 15: "both the aged and ancient men are among us, much elder than your fathers." Second, he mocks the confidence of the king: "Where now?" And first, the question: below, 47: "let them stand and save you"; second, the answer: "the fools have withered away," that is, have failed, as above; third, he mocks the cowardice of the deceived people: "they have deceived." Here he does three things. First he sets down the deception of the wise: "they have deceived the corner," that is, the kingdom, in which many are joined together as walls at a corner. Below, 47: "your wisdom and your knowledge have deceived you." Second, the permission of God: "the Lord has mingled" — this is often said metaphorically. "A spirit of dizziness," that is, of error, after the manner of one who suffers vertigo. 3 Kings, last chapter: "the Lord has put a lying spirit in the mouth of all your prophets." Third, the error of the people itself: "and to err." "Head" — namely, neither as to the beginning; "tail" — neither as to the end; "bowing down" — as to the old man; "holding back" — as to the young man, who needs restraint, or one given to wantonness. 2 Tim. 3: "but evil men and seducers shall grow worse." "In that day." Here he threatens the fear of the strong. And first he sets down the fear: "as women," weak and feeble. Jer. 51: "their strength is devoured, and they have become as women." Second, the reason: "the land of Judah shall be" — namely, the memory of the evils which they did to them, turning them away from the worship of God, on account of which they shall know that they have incurred the wrath of God. 1 Mach. 6: "now I remember the evils that I did in Jerusalem." "In that day." Here the resulting benefit, or consolation, is set down — namely, their conversion. And first, a threefold sign of the conversion: of which the first is the oath, "swearing." Below, 65: "he who swears," etc., "shall swear by the God, Amen: because the former distresses are delivered to oblivion." "The city of the sun" — Heliopolis. "The language of Canaan" — which borders on the language of the Jews, so that they might also agree in language with the people of God. For among these certain Syrians were transplanted by Nebuchadnezzar, who kept their own language. The second sign is a sacred building: "an altar of the Lord, and a monument" — because they worshiped many gods, as is said in Acts 17. This (some say) was fulfilled in the time of the Maccabees, when, many Jews fleeing into Egypt, Onias, wishing to fulfill this prophecy, built an altar against the precept of the Law, which is against that word of Exod. 20: "you shall not build me an altar," etc.; concerning which it is argued in Dan. 11: "the children also of the transgressors of your people shall lift themselves up to fulfill the vision, and they shall fall." Whence it is clear that this is not the meaning, but rather it concerns an altar to be built for Christian worship. The third sign is that they call upon the help of God: "they shall cry out"; "a savior" — Jesus. Ps. 90: "he cried to me." Second, he sets down the manner of the conversion: first, as to the reception of the faith, "and he shall be known": Jer. 31: "all shall know me, from the least even to the greatest, says the Lord"; second, as to the offering of sacrifices and vows, "and they shall worship": Malachi 1: "in every place there is offered to my name a clean oblation"; third, as to the remission of sins: "and he shall strike" — first, through many punishments; "and he shall heal" — from sin. Job 5: "he wounds and cures; he strikes, and his hands shall heal." Third, he sets down the threefold effect of the conversion: namely, peace: "in that day there shall be a way," which before could not be, on account of the different kingdoms, which at the birth of the Lord were joined together under the Romans. "They shall serve" — in trading with one another; or because Syrian soldiers were in the legions of the Romans for the guarding of Egypt. Above, 2: "nation shall not lift up sword against nation." Second, he promises the second effect, the truth of the faith: "in that day the third" — together, and serving the Romans equally, and in unity of faith. John 10: "there shall be one fold and one shepherd." Rom. 10: "there is no distinction of Jew and Greek." Third, he sets down the third effect, namely the divine blessing: "it shall be" — namely, Israel — "a blessing," because through the apostles the whole world received the blessing of God. "An inheritance," because he was born there, and fulfilled the mysteries of our salvation there. Ps. 113: "he blessed the house of Israel."”

“Surely the princes of Zoan are fools,.... Zoan was a very ancient city of Egypt, it was built within seven years of Hebron in the land of Judah, Num 13:22 here it was that the Lord did those miracles, by the hands of Moses and Aaron, before Pharaoh and his people, in order to oblige him to let Israel go, Psa 78:12 by which it appears that it was then the royal city, as it seems to have been now; since mention is made of the princes of it, who usually have their residence where the court is. The Targum, Septuagint, and Vulgate Latin versions, call it Tanis, which was the metropolis of one of the nomes or provinces of Egypt, called from it the Tanitic nome (q); near it was one of the gates of the Nile, which had from it the name of the Tanitic gate (r); the princes of this place, the lords of this nome, though they had princely education, acted a foolish part, in flattering their sovereign, as afterwards mentioned, and in putting him upon doing things destructive to his kingdom and subjects: the counsel of the wise counsellors of Pharaoh is become brutish; the men of whose privy council were esteemed very wise, and greatly boasted of, and much confided in; and yet the counsel they gave him were such as made them look more like brutes than men: how say ye unto Pharaoh; the then reigning prince, for Pharaoh was a name common to all the kings of Egypt. Some think their king Cethon is meant, said to be a very foolish king: others Psammiticus; which seems more likely; though there is no need to apply it to any particular king, they being used to say what follows to all their kings: I am the son of the wise; suggesting that wisdom was natural and hereditary to him; though this may not merely respect his immediate ancestors, but remote ones, as Menes or Mizraim, the first king of Egypt, to whom is attributed the invention of arts and sciences; and his son Thoth, the same with Hermes, the Mercury of the Egyptians. The Septuagint, Syriac, and Arabic versions, make these words to be spoken by the wise counsellors of themselves, "we are the sons of wise men", and so the next clause; likewise Aben Ezra and Jarchi, also the Targum: the son of ancient kings? according to these, it is spoken to Pharaoh thus, "and thou the son of kings of old"; of Ham, Mizraim, Thoth, &c.; the Egyptians boasted much of the antiquity of their kingdom and kings; and they say, from their first king Menes, to Sethon the priest of Vulcan, who lived about the time of this prophecy, were three hundred and forty one generations or ages of men, in which were as many kings and priests; and three hundred generations are equal to ten thousand years (s); and so many years, and more, their kings had reigned down to the prophet's time; which was all vain boasting, there being no manner of foundation for it. Vitringa renders it the son of ancient counsellors; this, as the former, being spoken by the counsellors, not of Pharaoh, but themselves. (q) Herodot. l. 2. c. 166. Plin. l. 5. c. 9. Ptolem. Geogr. l. 4. c. 5. (r) Ptolem. ib. Plin. l. 5. c. 10. (s) Herodot. l. 2. c. 142.”

“Zoan--The Greeks called it Tanis, a city of Lower Egypt, east of the Tanitic arms of the Nile, now San; it was one the Egyptian towns nearest to Palestine (Num 13:22), the scene of Moses' miracles (Psa 78:12, Psa 78:43). It, or else Memphis, was the capital under Sethos. I am . . . son of the wise . . . kings--Ye have no advice to suggest to Pharaoh in the crisis, notwithstanding that ye boast of descent from wise and royal ancestors. The priests were the usual "counsellors" of the Egyptian king. He was generally chosen from the priestly caste, or, if from the warrior caste, he was admitted into the sacred order, and was called a priest. The priests are, therefore, meant by the expression, "son of the wise, and of ancient kings"; this was their favorite boast (HERODOTUS, 2.141; compare Amo 7:14; Act 23:6; Phi 3:5). "Pharaoh" was the common name of all the kings: Sethos, probably, is here meant.”

“The prophet now dwells upon the punishment which falls upon the pillars of the land, and describes it in Isa 19:11-13 : "The princes of Zoan become mere fools, the wise counsellors of Pharaoh; readiness in counsel is stupefied. How can ye say to Pharaoh, I am a son of wise men, a son of kings of the olden time? Where are they then, thy wise men? Let them announce to thee, and know what Jehovah of hosts hath determined concerning Egypt. The princes of Zoan have become fools, the princes of Memphis are deceived; and they have led Egypt astray who are the corner-stone of its castes." The two constructives יעצי חכמי do not stand in a subordinate relation, but in a co-ordinate one (see at Psa 78:9 and Job 20:17; compare also Kg2 17:13, Keri), viz., "the wise men, counsellors of Pharaoh," (Note: Pharaoh does not mean "the king" (equivalent to the Coptic π-ουρο), but according to Brugsch, "great house" (Upper Egyptian perâa, Lower Egyptian pher-âo; vid., aus dem Orient, i. 36). Lauth refers in confirmation of this to Horapollo, i. 62, ὄφις καὶ οἶκος μέγας ἐν μέσω αὐτοῦ σημαίνει βασιλέα, and explains this Coptic name for a king from that of the Οὐραῖος (βασιλίσκος) upon the head of the king, which was a specifically regal sign.) so that the second noun is the explanatory permutative of the first. Zoan is the Tanis of primeval times (Num 13:22), which was situated on one of the arms through which the Nile flows into the sea (viz., the ostium Taniticum), and was the home from which two dynasties sprang. Noph (per aphaer. = Menoph, contracted into Moph in Hos 9:6) is Memphis, probably the seat of the Pharaohs in the time of Joseph, and raised by Psammetichus into the metropolis of the whole kingdom. The village of Mitrahenni still stands upon its ruins, with the Serapeum to the north-west. (Note: What the lexicons say with reference to Zoan and Noph needs rectifying. Zoan (old Egyptian Zane, with the hieroglyphic of striding legs, Copt. 'Gane) points back to the radical idea of pelli or fugere; and according to the latest researches, to which the Turin papyrus No. 112 has led, it is the same as Αὔαρις (Ἄβαρις), which is said to mean the house of flight (Ha-uare), and was the seat of government under the Hykshōs. But Memphis is not equivalent to Ma-m-ptah, as Champollion assumed (although this city is unquestionably sometimes called Ha-ka-ptah, house of the essential being of Ptah); it is rather equivalent to Men-nefer (with the hieroglyphic of the pyramids), place of the good (see Brugsch, Histoire d'Egypte, i. 17). In the later language it is called pa-nuf or ma-nuf, which has the same meaning (Copt. nufi, good). Hence Moph is the contraction of the name commencing with ma, and Noph the abbreviation of the name commencing with ma or pa by the rejection of the local prefix; for we cannot for a moment think of Nup, which is the second district of Upper Egypt (Brugsch, Geogr. i. 66). Noph is undoubtedly Memphis.) Consequently princes of Zoan and Memphis are princes of the chief cities of the land, and of the supposed primeval pedigree; probably priest-princes, since the wisdom of the Egyptian priest was of world-wide renown (Herod. ii. 77, 260), and the oldest kings of Egypt sprang from the priestly caste. Even in the time of Hezekiah, when the military caste had long become the ruling one, the priests once more succeeded in raising one of their own number, namely Sethos, to the throne of Sais. These magnates of Egypt, with their wisdom, would be turned into fools by the history of Egypt of the immediate future; and (this is the meaning of the sarcastic "how can ye say") they would no longer trust themselves to boast of their hereditary priestly wisdom, or their royal descent, when giving counsel to Pharaoh. They were the corner-stone of the shebâtim, i.e., of the castes of Egypt (not of the districts or provinces, νομοί); but instead of supporting and defending their people, it is now very evident that they only led them astray. התעוּ, as the Masora on Isa 19:15 observes, has no Vav cop.”
