If Esau comes and attacks one camp, then the other camp can escape
- Genesis 33:1-3
1Now Jacob looked up and saw Esau coming toward him with four hundred men. So he divided the children among Leah, Rachel, and the two maidservants. 2He put the maidservants and their children in front, Leah and her children next, and Rachel and Joseph at the rear. 3But Jacob himself went on ahead and bowed to the ground seven times as he approached his brother.
- Matthew 10:16
16Behold, I am sending you out like sheep among wolves; therefore be as shrewd as snakes and as innocent as doves.
