[Ibn Ezra on Exodus 7:3, "I will harden Pharaoh's heart."] Many have wondered how Pharaoh can be considered to have sinned if God hardened his heart. Some great minds reply that what God did was to strengthen Pharaoh's ability to bear his troubles. My answer is that God gives man wisdom and plants within his heart the intelligence to receive a higher power that enables him to increase his pleasure, or to lessen his pain. I will explain this further in my comments to 33:23 and Deut. 5:26. [Now let's find Ibn Ezra on Exodus 33:23, when God tells Moses "You shall see My back."] The remark of our Sages that God showed him the knot on His phylacteries is correct, but not literally so, as contemporary scholars think. It is a profound mystery. Saadia takes this to mean "You will see the end of My light, but you cannot see its beginning." In my opinion, the text speaks of God here in human terms, as it customarily does. For we know quite clearly that God has no material body and therefore cannot be seen, since the eye can see only material things. So I think Moses does not mean "behold" literally. After all, "The LORD would speak to Moses face to face" (v. 11) does not mean that God has a mouth. Rather, He spoke with him through a kind of direct communication for which "speech" is merely a metaphor. "As one man speaks to another" (v. 11) merely means that Moses communicated directly with the Creator, without an angelic intermediary. "But My face must not be seen." The purpose of Moses' request was to unite with the "forms" that have no material content, for they are the ladder by which one ascends to the Sublime. No living being can do this, because of his materiality; hence "man may not see Me and live" (v.20). You must understand that every compound body has a "face" and a "back." But the sun, the greatest and most glorious of all created things, has no face and no back. Nor do the stars, [Carasik: "Another reading has "the glorious ones," that is, the angels."] much less their Creator. So every soul is attached to God, and He alone has no beginning and no end. The soul that is attached to Him has no end from the perspective of God. But it does have a beginning, the moment at which it became attached to God. [Carasik: "Souls are created at one moment in time but then continue to exist forever."] [Ibn Ezra continues.] With regard to these upper realms of sun, moon, and stars, "He made them endure forever, establishing an order that shall never change" (Ps. 148:6). They were created this way for the sake of those who would be subject to their influence. But the upper worlds cannot change their motions in any way. So one who prays to the stars achieves nothing. Whatever is decreed for him by their position at his birth is going to happen--unless he is protected by some Power higher than theirs. [Ibn Ezra continues.] Let me explain with a story. It was in the stars that a river would rise and flood a certain city, drowning its inhabitants. A prophet came and warned them to repent before their day of evil, which they whole-heartedly did. Once they had cleaved to God, He put into the hearts of the people of the city to go out of the city to pray to Him. It was on the very day they did so that the river suddenly rose (as rivers do) and flooded the city. What God had decreed to happen in nature did not change its course--and yet He saved them. [Ibn Ezra continues.] Consider that the planets run like horses on a highway--not with the purpose of doing good or evil, but simply running on their way. Imagine a blind man on the road, who cannot see when the horses are running to the right and when they are running to the left. He must rely on someone with sight to protect him by leading him to this side or that. The horses do not change their course, but the blind man is saved. In just this way, "the LORD took you and brought you out of Egypt, that iron blast furnace, to be His very own people" (Deut. 4:20). It is in this respect that Israel is "distinguished ... from every people on the face of the earth" (v. 16). (From "The Commentator's Bible: the JPS Miqra'ot gedolot Exodus", editor M. Carasik (2005) JPS, pp. 46 and 300-301.)
