Then Jacob, lifting up his eyes, saw Esau coming with his four hundred men. So he made a division of the children between Leah and Rachel and the two women-servants.

For this reason the children of Israel, even today, never take that muscle in the hollow of the leg as food, because the hollow of Jacob's leg was touched.
