Genesis 32:18-20

18— then thou shalt say, Thy servant Jacob's: it is a gift sent to my lord, to Esau. And behold, he also is behind us.

19And so commanded he the second, and the third, and all that followed the droves, saying, According to this word shall ye speak to Esau when ye find him.

20And, moreover, ye shall say, Behold, thy servant Jacob is behind us. For he said, I will propitiate him with the gift that goes before me, and afterwards I will see his face: perhaps he will accept me.
