Isaiah 49:23 Douay-Rheims

And kings shall be thy nursing fathers, and queens thy nurses: they shall worship thee with their face toward the earth, and they shall lick up the dust of thy feet. And thou shalt know that I am the Lord, for they shall not be confounded that wait for him.

“Hear, O islands, etc. In this part he pursues the order of the liberation more specifically; and concerning this he does two things. First the people confesses the benefits received; second it receives the promise of things to come, there, I said: in vain, etc. Concerning the first, four benefits are confessed. First, the privilege of the divine election; and it continues why the prophet had above enjoined the people, that they should announce it. Whence immediately is subjoined the voice of the people announcing, and saying, Hear. From the womb, choosing me in the fathers themselves. Ps. 21: From the womb of my mother, God, etc. Second, the efficacy of prayer: and he set the mouth, prayer, as a sword, penetrating even to the ears of God and the depths of his mercy, Eph. ult.: the sword of the spirit, etc. Third, the help of divine protection: in the shadow, that is, under the protection of his power, as an archer hides a chosen arrow, to preserve it. Ps. 16: under the shadow of thy wings, etc.; Ps. 26: he hath hidden me in his tabernacle, etc. Fourth, the glory of the divine power: and he said to me: in thee will I glory; through the great things shown in thee I will appear glorious. Above, 43: every one that calleth upon my name, etc. According to others, this is the voice of Cyrus, whose name was foretold by Isaiah above, 45, before he was born; whose threatening words were as a sword, and he was protected lest his grandfather should kill him, and was kept as a chosen arrow for the appointed time; to whom it was announced that the people of Israel was the servant of God. Otherwise it is expounded of Christ; whose name was foretold by the Angel; the word of preaching, a sword piercing hearts; protected, on account of the weakness of the flesh, by the power of the divinity, and chosen among all for the fulfilling of the salvation of the human race. And he is called Israel, because he was born of the people of Israel according to the flesh. I said: here the Lord promises future benefits: and first he promises the prophet Isaiah exaltation; second, to the people liberation, there, thus saith the Lord the redeemer, etc. Concerning the first, two things. First is set down the allegation of the prophet, setting forth his labor in preaching, although through the fault of the hearers no fruit followed: and he concludes: therefore my judgment, on my behalf, is with the Lord, before him, and my work, as pleasing to him. Jer. 6: the founder hath melted in vain, etc. Second, he sets down God's response: and now thus saith the Lord: and first is signified the acceptance of the allegation, that I may bring back, as if to say: choosing me from the womb of my mother for this, that I might recall his people to him. And yet Israel shall not altogether be gathered, to him through my preaching. And yet I am glorified, etc.; Habac. 3: God, the Lord, is my strength, etc. Second, the response itself is set down, and he said: it is a small thing, as if to say: so greatly will I honor thy ministry that not only among the Jews, but among all the nations, my salvation shall be announced through thee. Rom. 3: is he the God of the Jews only? etc. This too is plainly expounded of Christ, who by his preaching and the consummation of his death made little fruit among the Jews, but enlightened and saved the nations. Likewise also of Cyrus, though more forcedly, who through his kindnesses, according to the Lord's intention, recalled the people to the worship of God, and yet did not succeed, to whom dominion over many nations was given by God. Thus saith the Lord the redeemer, etc. Here he promises liberation: and concerning this he does two things. First he promises liberation; second he excludes their doubt, there, and Sion said, etc. Concerning the first, three things. First, the things preceding liberation, namely the veneration of the Jews, which was the cause of the liberation; recalling their former contempt: contemptible, on account of the people's weakness; abominable, on account of the singularity of their worship; a servant, on account of subjection to diverse nations, above, 18: to a nation rent asunder, etc.; and he sets down the veneration itself: kings shall see the great things I will show for thee, and shall adore, as, according to the letter, Nabuchodonosor, Dan. 2, and Cyrus, and his other princes honored Esdras. Another preamble is the exaltation of the liberating king, namely Cyrus: in an acceptable time, and he does not determine the time of the exaltation: acceptable, when it shall please me to save my people, I have heard, exalting thee into a kingdom, according to thy desire, and the fruit of the exaltation: and I have preserved, etc., for the fulfilling of the covenant of my people. Be revealed, that is, be enlightened. Or of Christ, who in his passion was despised, and judged as it were a servant. Below, 53: we saw him despised, etc., but afterward, according to the letter, adored by kings. Ps. 71: all kings shall adore him, etc.; in an acceptable time, namely the time of grace. 2 Cor. 6: behold, now is the time, etc. Second, he sets down the things consequent upon the liberation, promising to the liberated an abundance of good things: they shall feed in the ways; that is, they shall enjoy consolations as abundantly as sheep enjoy pastures, when they are found even in the way, beyond the usual. Ezech. 34: they shall rest in the grass, etc.; as to the absence of evils, both of want, he shall not hunger, etc., and of harm inflicted, the heat, of tribulation; and the sun, the tyrant causing it. Ps. 120: the sun shall not burn by day, etc.; and he assigns the cause of both. Because he that is merciful, etc.; of waters, of consolations. Ps. 22: the Lord ruleth me. Third, he promises the liberation itself, setting down the preparation of the ways: and I will make all the mountains; that is, the princes will help you to return. Above, 40: every valley shall be filled, etc.; setting down also the return of the captives: behold these from afar, from the east, the sea, the west. Jer. 31: I will bring them from the north, etc.; he sets down also the giving of thanks: praise, ye heavens, etc.; Ps. 68: let the heavens praise him, etc. And Sion said, etc. Here he excludes their doubt: and first that which arose from the divine indignation; second that which arose from their dejection, there, and thou shalt say in the heart, etc.; third that which arose from the power of the enemies, there, shall it be taken away, etc. Concerning the first, two things. First he sets down the doubt: hath forsaken, without help; and therefore I cannot hope for liberation. Baruch 4: I am forsaken, etc.; second he excludes it by the likeness of a mother: is it possible, etc.; Jer. 31: if a son honorable, etc.; third he applies the promise concerning the restoration of the city: and first as to the rebuilding of the walls, setting down the divine purpose: behold, in my hands; as if to say: thus I hold thee in memory, as one who writes, or makes some sign on his hand, that he may be mindful of some thing. Thy walls; as if to say, now I see the rebuilding of thy walls. Job 37: he hideth in the hands, etc.; Ps. 89: a thousand years before the eyes, etc.; and the manner of the fulfillment: builders have come, that is, rebuilders, namely Zorobabel, and Jesus, and others, already in my eyes; the scatterers, the Chaldeans. Zach. 4: the hands of Zorobabel, etc. Second, as to the habitation of men: and concerning this he does three things. First, the gathering together of the citizens: lift up round about, etc.; Baruch 4: look about, Jerusalem, etc. Second, the re-inhabiting of the city, showing that it shall be inhabited. As I live, the manner of an oath; as with an ornament — as a bride with garments, so the city is adorned with citizens. Below, 61: he hath clothed me with the garment of salvation, etc.; showing that it shall be filled with inhabitants: for the desert places, as to inhabitants, the solitudes, as to the tillers, the ruins, as to the destroyed walls. Zach. 2: it shall be inhabited without a wall, etc.; he shows also that it shall be emptied of enemies: and far, etc. Third, he foretells the multitude of the inhabitants: still shall the children of sterility say, that is, those who were born when thou didst believe thyself barren, emptied of inhabitants. Below, 54: enlarge the place of the tent, etc. And thou shalt say in the heart, etc. Here he excludes the second doubt: and first he sets down the wonder, and thou shalt say, out of wonder: barren, because there were not in me men who could beget children; destitute, of divine help. Below, 66: who hath ever heard such, etc. Second he excludes the doubt, setting down the manner of the multitude of the inhabitants: thus saith the Lord: as to four things. First, as to the divine inspiration: behold I will lift up the hand, as it were making a sign; above, 11: he shall lift up a sign among the nations, etc. Second, as to the honorable bringing back: and they shall bring in the arms, in which is signified the help which they had from the nations. Kings, foster-fathers, providing for thee in necessities. Baruch 5: the Lord will bring them to thee, etc. Third, as to the exaltation of the liberated: with the face to the earth, this especially at the time of the Machabees; below, 40: they shall come to thee bowed down, etc. Fourth, he assigns the reason for this: and thou shalt know that I, etc.; Ps. 70: in thee, O Lord, have I hoped, let me not be confounded, etc. Shall it be taken away. Here he excludes the third doubt: and first he sets it down, from the strong, Nabuchodonosor; Matth. 12: or how can one enter, etc. Second he excludes it: for thus he saith, first setting down the benefit of the liberation: the captivity, namely of the Jews. Job 29: I broke the jaws of the wicked one, etc.; second, the manner of the liberation, setting down the destruction of the enemies. But them, namely the Chaldeans, they judged, unjustly. Soph. 3: I will kill, etc.; and he sets down the determination of the punishment: and I will feed: either on account of dissension, as above, 9: every man the flesh of the arm, etc., or on account of the multitude of the dead, while the mouth of one fell upon the blood of another, as if he would drink: or on account of famine. Third, he sets down the fruit of the liberation: and all flesh shall know, etc.; above, 40: all flesh shall see, etc.”

“And kings shall be thy nursing fathers, and their queens thy nursing mothers,.... Who shall show favour and respect to the church and people of God, grant them liberty, and protect and defend them in their religious privileges: for this is to be understood not figuratively of apostles and apostolical men, as Jerom, who are kings and priests unto God, and who feed the church with the milk of the word, and the breasts of ordinances; but literally of the kings and queens of the earth; and is thought to have had its fulfilment, at least in part, in Cyrus, Ahasuerus, Esther, and others; but more so in Christian kings and queens, as Constantine and Helena, Theodosius and Placilla, and others; and will have a far greater accomplishment in the latter day glory; see Isa 60:3, they shall bow down toward thee with their faces toward the earth; which expresses the great veneration and respect these great personages shall have for the church of God, and their entire submission and subjection to the Gospel of Christ, and the ordinances of it, and to the laws and discipline of his house; for they shall now become members of the Christian church, and be entirely under the government of it, as to religious things; see Rev 3:9. and lick up the dust of thy feet; the allusion is to the eastern nations, especially the Persians, who, in the adoration of their kings, used to kiss the ground they stood on, and seemed to lick, if they did not, the dust that was about them; and it expresses the very low submission of kings and princes to the church, and their high veneration of it; their willingness to do the meanest office for the good of it, and their great regard and affection for the meanest of its members, the dust of Zion; see Psa 72:9, and thou shalt know that I am the Lord; the King of kings, and Lord of lords, who has the hearts of all men, even of kings, in his hands, and can turn them, and bring them to a thorough submission to his will; and who is able to accomplish all his promises, and is true and faithful to them; this will be known and owned by the church, when the above things have their accomplishment: for they shall not be ashamed that wait for me; or for my salvation, as the Targum; for favours from him; for the light of his countenance; for the discoveries and application of pardoning grace; for the performance of promises; for answers of prayer; for his spiritual coming, and for eternal glory and happiness; these shall not be ashamed of him for whom they wait, nor of their hope and expectation of him, nor at his coming.”

“Nurses. The Persian kings favoured the captives. The greatest monarchs bow before the prelates of the Church, (Menochius) and kiss the Pope’s toe. They venerate relics, (Haydock) and greatly enrich the Church. (Calmet)”

“lick . . . dust--that is, kiss thy feet in token of humble submission. for they . . . not . . . ashamed . . . wait for me--The restoration of Israel shall be in answer to their prayerful waiting on the Lord (Isa 30:18-19; Psa 102:16-17; Zac 12:10; Zac 14:3).”

“Such affectionate treatment does the church receive, which is assembling once more upon its native soil, whilst kings and their consorts hasten to serve the re-assembled community. "And kings become thy foster-fathers, and their princesses they nurses: they bow down their face to thee to the earth, and they lick the dust of thy feet; and thou learnest that I am Jehovah, He whose hoping ones are not put to shame." As foster-fathers devote all their strength and care to those entrusted to them, and nurses nourish children from the very marrow of their own life, so will kings become the shelterers of Zion, and princesses the sustainers of her growth. All that is true in the regal headship of the church will be realized, and all that is false in regal territorialism will condemn itself: "vultu in terram demisso adorabunt te et pulverem pedum tuorum lingent" (Jerome). They do homage to the church, and kiss the ground upon which she stands and walks. According to Isa 45:14, this adoration belongs to the God who is present in the church, and points the church itself away from all thought of her own merits to Jehovah, the God of salvation, cui qui confidunt non pudefient (וידעתּ with an auxiliary pathach, like יגעתּ in Isa 47:15; Ges. 65, 2: אשׁר with the first person made into a relative as in Isa 41:8; Ges. 123, 1, Anm. 1). Observe, however, that the state will not be swallowed up by the church - a thing which never will occur, and is never meant to occur; but by the state becoming serviceable to the church, there is realized a prelude of the perfected kingdom of God, in which the dualism of the state and the church is entirely abolished.”
