32:9 Then Jacob prayed, “O God of my father Abraham, God of my father Isaac, O Lord, you said to me, ‘Return to your land and to your relatives and I will make you prosper.’ 32:10 I am not worthy of all the faithful love you have shown your servant. With only my walking stick I crossed the Jordan, but now I have become two camps. 32:11 Rescue me, I pray, from the hand of my brother Esau, for I am afraid he will come and attack me, as well as the mothers with their children.
