Rashi explains that Jacob prepared to meet Esau in three ways: he prayed, he brought him gifts, and he readied for war. However, the Torah never uses the language of prayer. Instead, it states And Jacob said: “God of my father Abraham and God of my father Isaac! LORD who has said to me, ‘Return to your land and your birthplace, and I will deal well with you.’ Abrabarnel explains that although Jacob was afraid, he also understood that it was impossible that his parents and grandparents endured so much for God and it would all come to an end with him. Therefore the Torah does not state that he prayed but rather he invoked a fact: And Jacob said: God of my father Abraham and God of my father Isaac.
