And he said: Thus said the Lord: At midnight I will enter into Egypt.

“ויאמר משה כה אמר ה AND MOSES SAID, THUS SAITH THE LORD — Whilst he was still standing before Pharaoh this prophecy was spoken to him, because after he left him, he did not see his face again (Exodus Rabbah 18:1). כחצות הלילה means, WHEN THE NIGHT IS DIVIDED (i. e., when midnight arrives). כחצות is an infinitive with prefix, of similar form to, (1 Kings 18:36) בעלות, “when went up” and (Psalms 124:3) “when their wrath was kindled (בחרות)”. This is its literal meaning which fits in with the sense, for חצות is not a noun, being another form of חֵצִי (when the meaning would be about midnight I will go out etc.”, for this does not fit in with the sense, since God would certainly have stated exactly when He would do this). But our Rabbis took it in this sense and explained it as meaning “about the middle of the night”, and they asserted that Moses said כחצות “about midnight”, which implies near to it — either just before it or just after it, and he did not say בחצות “at midnight” (as God had bidden him say) because he feared lest Pharaoh’s astrologers might make a mistake as regards the time when the slaughter of the firstborn actually took place, thinking that it was a little earlier or later than midnight, and would say, in consequence of this error, “Moses is a liar!” (cf. Berakhot 4a).”

“AND MOSES SAID: THUS SAITH THE ETERNAL: ABOUT MIDNIGHT WILL I GO OUT INTO THE MIDST OF EGYPT. Moses said this to Pharaoh and to his servants, as he mentioned at the end of his words, And all these thy servants shall come down unto me. Now he did not explain on what night this plague will take place, since this Divine communication to Moses and the transmission thereof to Pharaoh happened before the first of Nisan, the first of Nisan. In my opinion, this is to be explained on the basis of that which Ramban wrote in Seder Shemoth (4:21), that at the very first time that Moses came before Pharaoh, he warned him of the last plague which will force him to let the people go. In that case, the Divine communication to Moses and the transmission of it to Pharaoh did indeed take place before the first of Nisan. The verse here, yet one plague more will I bring upon Pharaoh, must then be understood in the sense that G-d told Moses that the time had come for the final plague of which He had told him in the beginning and which Moses had related to Pharaoh. See also my Hebrew commentary, p. 323, for further discussion of this problem. and when he said about midnight, he did not yet know on which night it would be. Thus Moses did not inform them of the specific night on which this plague would take place, but instead he said in kindled anger, “I will see thy face again no more. It is you who will call upon me at about midnight to go out from your country, and your servants will bow down to me.” In the second section He elucidated to Israel, And I will go through the land of Egypt in that night, and in the third section Scripture states, And it came to pass at midnight,, Verse 29. i.e., the night mentioned when they were eating the paschal lamb.”

“Warning is here given to Pharaoh of the last and conquering plague which was now to be inflicted. This was the death of all the first-born in Egypt at once, which had been first threatened (Exo 4:23, I will slay thy son, thy first-born), but is last executed; less judgments were tried, which, if they had done the work would have prevented this. See how slow God is to wrath, and how willing to be met with in the way of his judgments, and to have his anger turned away, and particularly how precious the lives of men are in his eyes: if the death of their cattle had humbled and reformed them, their children would have been spared; but, if men will not improve the gradual advances of divine judgments, they must thank themselves if they find, in the issue, that the worst was reserved for the last. 1. The plague itself is here particularly foretold, Exo 11:4-6. The time is fixed - about midnight, the very next midnight, the dead time of the night; when they were all asleep, all their first-born should sleep the sleep of death, not silently and insensibly, so as not to be discovered till morning, but so as to rouse the families at midnight to stand by and see them die. The extent of this plague is described, Exo 11:5. The prince that was to succeed in the throne was not too high to be reached by it, nor were the slaves at the mill too low to be taken notice of. Moses and Aaron were not ordered to summon this plague; no I will go out, saith the Lord, Exo 11:4. It is a fearful thing to fall into the hands of the living God; what is hell but this? 2. The special protection which the children of Israel should be under, and the manifest difference that should be put between them and the Egyptians. While angels drew their swords against the Egyptians, there should not so much as a dog bark at any of the children of Israel, Exo 11:7. An earnest was hereby given of the difference which shall be put in the great day between God's people and his enemies: did men know what a difference God puts, and will put to eternity, between those that serve him and those that serve him not, religion would not seem to them such an indifferent thing as they make it, nor would they act in it with so much indifference as they do. 3. The humble submission which Pharaoh's servants should make to Moses, and how submissively they should request him to go (Exo 11:8): They shall come down, and bow themselves. Note, The proud enemies of God and his Israel shall be made to fall under at last (Rev 3:9), and shall be found liars to them, Deu 33:29. When Moses had thus delivered his message, it is said, He went out from Pharaoh in a great anger, though he was the meekest of all the men of the earth. Probably he expected that the very threatening of the death of the firstborn would have induced Pharaoh to comply, especially as Pharaoh had complied so far already, and had seen how exactly all Moses's predictions hitherto were fulfilled. But it had not that effect; his proud heart would not yield, no, not to save all the firstborn of his kingdom: no marvel that men are not deterred from vicious courses by the prospects given them of eternal misery in the other world, when the imminent peril they run of the loss of all that is dear to them in this world will not frighten them. Moses, hereupon, was provoked to a holy indignation, being grieved (as our Saviour afterwards) for the hardness of his heart, Mar 3:5. Note, It is a great vexation to the spirits of good ministers to see people deaf to all the fair warnings given them, and running headlong upon ruin, notwithstanding all the kind methods taken to prevent it. Thus Ezekiel went in the bitterness of his spirit (Eze 3:14), because God had told him that the house of Israel would not hearken to him, Exo 11:7. To be angry at nothing but sin is the way not to sin in anger. Moses, having thus adverted to the disturbance which Pharaoh's obstinacy gave him, (1.) Reflects upon the previous notice God had given him of this (Exo 11:9): The Lord said unto Moses, Pharaoh shall not hearken to you. The scripture has foretold the incredulity of those who should hear the gospel, that it might not be a surprise nor stumbling-block to us, Joh 12:37, Joh 12:38; Rom 10:16. Let us think never the worse of the gospel of Christ for the slights men generally put upon it, for we were told before what cold entertainment it would meet with. (2.) He recapitulates all he had said before to this purport (Exo 11:10), that Moses did all these wonders, as they are here related, before Pharaoh (he himself was an eye-witness of them), and yet he could not prevail, which was a certain sign that God himself had, in a way of righteous judgment, hardened his heart. Thus the Jews' rejection of the gospel of Christ was so gross an absurdity that it might easily be inferred from it that God had given them the spirit of slumber, Rom 11:8.”

“And Moses said,.... To Pharaoh before he left him, when he had told him he should see his face no more; for the three preceding verses are to be read in a parenthesis, being placed here by the historian, as giving some light to this last discourse and transaction between Moses and Pharaoh: thus saith the Lord, about midnight will I go out into the midst of Egypt; perhaps to the capital and metropolis of it, which might stand in the midst of it, as usually does the royal city; or it may only signify that he would go into the very heart of it, and steer his course all around in every part and quarter of it, slaying the firstborn everywhere in all towns and cities throughout the kingdom, as follows; in order to which he is said to go out, either from the place where Moses used to go and pray to him, and where he met him and gave him his orders and instructions, or out of the land of Goshen, where he dwelt among the Israelites; or rather it only signifies the manifestation of himself in some work and action of his, the exertion of his power in inflicting punishment for sin: thus God is sometimes said to go forth out of his place when he is about to exercise judgment in the earth; for this must be understood consistent with his omnipresence, see Isa 26:21 and this was to be done about midnight, the middle of the night following the present day, which was the fourteenth of the month of Abib or Nisan; it was in the morning of that day Moses had this discourse with Pharaoh, and in the evening of it the passover was kept, and about the middle of the night the firstborn were slain, as follows.”

“About midnight will I go out - Whether God did this by the ministry of a good or of an evil angel is a matter of little importance, though some commentators have greatly magnified it. Both kinds of angels are under his power and jurisdiction, and he may employ them as he pleases. Such a work of destruction as the slaying of the first-born is supposed to be more proper for a bad than for a good angel. But the works of God's justice are not less holy and pure than the works of his mercy; and the highest archangel may, with the utmost propriety, be employed in either.”

“Thus saith the Lord, About midnight--Here is recorded the announcement of the last plague made in the most solemn manner to the king, on whose hardened heart all his painful experience had hitherto produced no softening, at least no permanently good effect. will I go out into the midst of Egypt--language used after the manner of men.”

“Moses' address to Pharaoh forms the continuation of his brief answer in Exo 10:29. At midnight Jehovah would go out through the midst of Egypt. This midnight could not be "the one following the day on which Moses was summoned to Pharaoh after the darkness," as Baumgarten supposes; for it was not till after this conversation with the king that Moses received the divine directions as to the Passover, and they must have been communicated to the people at least four days before the feast of the Passover and their departure from Egypt (Exo 12:3). What midnight is meant, cannot be determined. So much is certain, however, that the last decisive blow did not take place in the night following the cessation of the ninth plague; but the institution of the Passover, the directions of Moses to the people respecting the things which they were to ask for from the Egyptians, and the preparations for the feast of the Passover and the exodus, all came between. The "going out" of Jehovah from His heavenly seat denotes His direct interposition in, and judicial action upon, the world of men. The last blow upon Pharaoh was to be carried out by Jehovah Himself, whereas the other plagues had been brought by Moses and Aaron. מצרים בּתוך "in (through) the midst of Egypt:" the judgment of God would pass from the centre of the kingdom, the king's throne, over the whole land. "Every first-born shall die, from the first-born of Pharaoh, that sitteth upon his throne, even unto the first-born of the maid that is behind the mill," i.e., the meanest slave (cf. Exo 12:29, where the captive in the dungeon is substituted for the maid, prisoners being often employed in this hard labour, Jdg 16:21; Isa 47:2), "and all the first-born of cattle." This stroke was to fall upon both man and beast as a punishment for Pharaoh's conduct in detaining the Israelites and their cattle; but only upon the first-born, for God did not wish to destroy the Egyptians and their cattle altogether, but simply to show them that He had the power to do this. The first-born represented the whole race, of which it was the strength and bloom (Gen 49:3). But against the whole of the people of Israel "not a dog shall point its tongue" (Exo 11:7). The dog points its tongue to growl and bite. The thought expressed in this proverb, which occurs again in Jos 10:21 and Judith 11:19, was that Israel would not suffer the slightest injury, either in the case of "man or beast." By this complete preservation, whilst Egypt was given up to death, Israel would discover that Jehovah had completed the separation between them and the Egyptians. The effect of this stroke upon the Egyptians would be "a great cry," having no parallel before or after (cf. Exo 10:14); and the consequence of this cry would be, that the servants of Pharaoh would come to Moses and entreat them to go out with all the people. "At thy feet," i.e., in thy train (vid., Deu 11:6; Jdg 8:5). With this announcement Moses departed from Pharaoh in great wrath. Moses' wrath was occasioned by the king's threat (Exo 10:28), and pointed to the wrath of Jehovah, which Pharaoh would soon experience. As the more than human patience which Moses had displayed towards Pharaoh manifested to him the long-suffering and patience of his God, in whose name and by whose authority he acted, so the wrath of the departing servant of God was to show to the hardened king, that the time of grace was at an end, and the wrath of God was about to burst upon him.”
