As a reward for the sanctification of the Holy Name, which Abraham had brought about when he refused to keep aught of the goods taken in battle, his descendants received two commands, the command of the threads in the borders of their garments, and the command of the latchets to be bound upon their hands and to be used as frontlets between their eyes. Thus they commemorate that their ancestor refused to take so much as a thread or a latchet. And because he would not touch a shoe-latchet of the spoils, his descendants cast their shoe upon Edom.
