Genesis 32:3-8

Jacob sent messengers on ahead to his brother Esau in the land of Seir, the region of Edom. He commanded them, “This is what you must say to my lord Esau: ‘This is what your servant Jacob says: I have been staying with Laban until now. I have oxen, donkeys, sheep, and male and female servants. I have sent this message to inform my lord, so that I may find favor in your sight.’” The messengers returned to Jacob and said, “We went to your brother Esau. He is coming to meet you and has four hundred men with him.” Jacob was very afraid and upset. So he divided the people who were with him into two camps, as well as the flocks, herds, and camels. “If Esau attacks one camp,” he thought, “then the other camp will be able to escape.”
