And the messengers returned to Jacob, saying, “We came to your brother, to Esau, and he is actually coming to meet you, and four hundred men are with him.” And Jacob was greatly afraid…Rashbam, the grandson of Rashi, insists that it was out of respect for Jacob that Esau came to meet him with so large a party. He sees a parallel between the language used here and the verse where God assures Moshe that Aaron is coming out to meet you, and when he sees you, his heart will rejoice. The human heart can be hard to read and so it was that both Jacob and Moshe miscalculated their brother’s feelings.
