Ya`akov lifted up his eyes, and looked, and, behold, Esav was coming, and with him four hundred men. He divided the children between Le'ah, Rachel, and the two handmaids.
He delivered them into the hands of his servants, every herd by itself, and said to his servants, *Pass over before me, and put a space between herd and herd.*
Therefore the children of Yisra'el don't eat the sinew of the hip, which is on the hollow of the thigh, to this day, because he touched the hollow of Ya`akov's thigh in the sinew of the hip.
