Genesis 33:1-3

Then Jacob lifted his eyes and looked, and behold, Esau was coming, and four hundred men with him. So he divided the children among Leah and Rachel and the two maids. He put the maids and their children in front, and Leah and her children next, and Rachel and Joseph last. But he himself passed on ahead of them and bowed down to the ground seven times, until he came near to his brother.
