Genesis 32:1-10 (Eve of the Theophany)
Jacob went on his way and the angels of God met him; and when Jacob saw them he said, "This is God's army!" So he called the name of that place Mahana'im. And Jacob sent messengers before him to Esau his brother in the land of Se'ir, the country of Edom, instructing them, "Thus you shall say to my lord Esau: Thus says your servant Jacob, 'I have sojourned with Laban, and stayed until now; and I have oxen, asses, flocks, menservants, and maidservants; and I have sent to tell my lord, in order that I may find favor in your sight.'" And the messengers returned to Jacob, saying, "We came to your brother Esau, and he is coming to meet you, and four hundred men with him." Then Jacob was greatly afraid and distressed; and he divided the people that were with him, and the flocks and herds and camels, into two companies, thinking, "If Esau comes to the one company and destroys it, then the company which is left will escape." And Jacob said, "O God of my father Abraham and God of my father Isaac, O LORD who didst say to me, 'Return to your country and to your kindred, and I will do you good,' I am not worthy of the least of all the steadfast love and all the faithfulness which thou hast shown to thy servant, for with only my staff I crossed this Jordan; and now I have become two companies.
