And he said,
Lay not your hand upon the lad, neither do you anything unto him: for now I know that you fear God, seeing you have not withheld your son, your only son from me.
All Commentaries on Genesis 22:12 Go To Genesis 22
Hilary of Poitiers
AD 368
Hence we are not permitted to doubt that the knowledge of God is adapted to the time rather than to the result of a change, since in connection with that which God knew it is a question of the opportune moment to divulge what is known rather than to acquire it. [This] we are also taught by the words that were spoken to Abraham: “Do not lay your hand on the boy, and do nothing to him, for I know now that you fear your God, and have not spared your beloved son for my sake.” Accordingly, God knows now, but to know something now is an admission of previous ignorance. Since it is a contradiction for God not to know that Abraham had been previously faithful to him and of whom it had been said, “Abraham believed God, and it was credited to him as justice,” that which he knew at this moment is the time when Abraham received this testimony, and not the time when God also began to acquire this knowledge. By bringing his son as a holocaust, Abraham manifested the love that he had for God. God was aware of it then when he speaks. And, since we are not to believe that he had been ignorant of it up to that moment, we must understand that he knew of it then because he speaks of it. Of the many passages in the Old Testament that contain references to the knowledge of God, we have cited only this one as an example that we may realize that God’s ignorance of anything does not arise from a lack of knowledge but from the occasion.
