Genesis 32:2-8

When he saw them, he exclaimed, “This is God’s military camp!” So he named that place Two Camps of Angels. Jacob sent messengers ahead to his brother Esau who was living in the land of Seir, the country of Edom. He instructed them, “Give this message from me to my master Esau, ‘I am your servant. I have lived with our uncle Laban all these years and have acquired sheep, cattle, donkeys, and both male and female servants. I send this message to you, my master, in the hope of finding favor in your eyes.’ ” When the messengers returned to Jacob, they informed him, “We gave your brother Esau your message, and he himself is coming here to meet you. In fact, he’s on his way now with four hundred men!” Gripped with fear to the point of panic, Jacob split all the people who were with him into two camps, and also the flocks, herds, and camels. He said to himself, “If Esau attacks the first camp and destroys them, at least the other camp will escape.”
