Genesis 32:6

4And he commanded them, saying, Thus shall ye speak unto my lord Esau; Thy servant Jacob saith thus, I have sojourned with Laban, and stayed there until now:

5And I have oxen, and asses, flocks, and menservants, and womenservants: and I have sent to tell my lord, that I may find grace in thy sight.

6And 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.

7Then 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;

8And said, If Esau come to the one company, and smite it, then the other company which is left shall escape.
