THE BINDING OF ISAAC ON THE ALTAR THE tenth trial was (as follows): "And it came to pass after these things, that God did prove Abraham" (Gen. 22:1). He tried Abraham each time in order to know his heart, whether he would be able to persevere and keep all the commandments of the Torah or not, and whilst as yet the Torah had not been given, Abraham kept all the precepts of the Torah, as it is said, "Because that Abraham obeyed my voice, and kept my charge, my commandments, my statutes, and my Torah" (Gen. 26:5). And Ishmael went repeatedly from the wilderness to see || his father Abraham.
