Genesis 32:8 (KJV)

And the messengers returned to Jacob, saying, We came to thy brother Esau, and also he cometh to meet thee, and four hundred men with him.

Then Jacob was greatly afraid and distressed: and he divided the people that was with him, and the flocks, and herds, and the camels, into two bands;

And said, If Esau come to the one company, and smite it, then the other company which is left shall escape.

And Jacob said, O God of my father Abraham, and God of my father Isaac, the Lord which saidst unto me, Return unto thy country, and to thy kindred, and I will deal well with thee:

I am not worthy of the least of all the mercies, and of all the truth, which thou hast shewed unto thy servant; for with my staff I passed over this Jordan; and now I am become two bands.
