“Though we sometimes hear the expression "God changed his mind" or even read in the figurative language of Scripture that "God repented," we interpret these sayings not in reference to the decisions determined on by almighty God but in reference to the expectations of man or to the order of natural causes.”

“And the Lord repented of the evil which he thought to do unto his people. He did not do what he threatened to do, and seemed to have in his thoughts and designs, but did what Moses desired he would, Exo 32:12 not that any of God's thoughts or the determinations of his mind are alterable; for the thoughts of his heart are to all generations; but he changes the outward dispensations of his providence, or his methods of acting with men, which he has been taking or threatened to take; and this being similar to what they do when they repent of anything, who alter their course, hence repentance is ascribed to God, though, properly speaking, it does not belong to him, see Jer 18:8. Aben Ezra thinks that the above prayer of Moses, which was so prevalent with God, does not stand in its proper place, but should come after Exo 32:31 for, to what purpose, says he, should Moses say to the Israelites, Exo 32:30 "peradventure I shall make an atonement for your sin": if he was appeased by his prayer before? "peradventure I shall make an atonement for your sin": if he was appeased by his prayer before? Exodus 32:15 exo 32:15 exo 32:15 exo 32:15And Moses turned, and went down from the mount,.... He turned himself from God, with whom he had been conversing forty days; his back was to the ascent of the mount, and he turned himself in order to go down; or "he looked" (g), as a man considers what is to be done, as Aben Ezra observes, and he saw that he was obliged to go down in haste: and the two tables of the testimony were in his hand; or hands, as in Exo 32:19 for they were, perhaps, as much as he could carry in both hands, being of stone, as in Exo 31:18 on which was written the law, the "testimony" of the will of God with respect to what was to be done or not done: the letters were written on both their sides, on the one side and on the other were they written; some think that the engraving of the letters was such, that it went through the stones, and in a miraculous manner the letters and lines were in a regular order, and might be read on the other sides; to which Jarchi seems to incline, saying, the letters might be read, and it was a work of wonders; others think that the letters were written both within and without, like Ezekiel's book of woes; that the same that was within side was written without, that so, when held up, they might be read by those that stood before and those that stood behind; but rather so it was that the whole was written within, some of the commands on the right, and some on the left, and so the tables might be clapped together as a book is folded. (g) "et aspexit", Pagninus.”

“And the Lord repented of the evil - This is spoken merely after the manner of men who, having formed a purpose, permit themselves to be diverted from it by strong and forcible reasons, and so change their minds relative to their former intentions.”

“Appeased. Yet of this Moses was not fully assured, and in effect only those who had been less guilty, were reprieved to be punished afterwards, ver. 30, 35. (Haydock)”
