Genesis 32:21 (KJV)

And he delivered them into the hand of his servants, every drove by themselves; and said unto his servants, Pass over before me, and put a space betwixt drove and drove.

And he commanded the foremost, saying, When Esau my brother meeteth thee, and asketh thee, saying, Whose art thou? and whither goest thou? and whose are these before thee?

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.

And he rose up that night, and took his two wives, and his two womenservants, and his eleven sons, and passed over the ford Jabbok.

And he took them, and sent them over the brook, and sent over that he had.

And Jacob was left alone; and there wrestled a man with him until the breaking of the day.

And when he saw that he prevailed not against him, he touched the hollow of his thigh; and the hollow of Jacob's thigh was out of joint, as he wrestled with him.

And he said, Let me go, for the day breaketh. And he said, I will not let thee go, except thou bless me.
