Genesis 32:18-20

Then thou shalt say, They be thy servant Jacob's; it is a present sent unto my lord Esau: and, behold, also he is behind us. And so commanded he the second, and the third, and all that followed the droves, saying, On this manner shall ye speak unto Esau, when ye find him. And say ye moreover, Behold, thy servant Jacob is behind us. For he said, I will appease him with the present that goeth before me, and afterward I will see his face; peradventure he will accept of me.
