Genesis 32:6-8

Young's Literal Translation

⁶ And the messengers turn back unto Jacob, saying, `We came in unto thy brother, unto Esau, and he also is coming to meet thee, and four hundred men with him;'

⁷ and Jacob feareth exceedingly, and is distressed, and he divideth the people who [are] with him, and the flock, and the herd, and the camels, into two camps,

⁸ and saith, `If Esau come in unto the one camp, and have smitten it -- then the camp which is left hath been for an escape.'
