Genesis 32:7

Jacob did not know whether Esau was friendly to him or not. Perhaps Esau was bringing 400 men so as to kill Jacob and all his people.

v9 And Jacob said, ‘God of my father Abraham! God of my father Isaac! You said to me, “Return to your country and to your relatives. I will do good things to you.” v10 I do not deserve any of the great love that you have shown to me, your servant. When I crossed this river Jordan, my only possession was my stick. But now because of your care I have become two groups of people and animals. v11 Please save me from my brother Esau. I am afraid of him. I am afraid that he will kill us all. He will kill the mothers and the children. v12 But you said, “I will do good to you. I will make your *descendants as many as the sand of the sea. The sand is many tiny pieces and nobody can count them.” ’
