창세기 32:28의 주석

?ויאמר ..מה שמך?, this question is only an opener for the dialogue that follows. We have several such examples, as in Genesis 3,9 where G’d asks Adam איכה?, “where are you?,” though He was perfectly aware of Adam’s whereabouts. Similarly, in Exodus 4,2 G’d asks Moses “what is this in your hand?,” knowing full well that Moses was holding a staff in his hand. Here too, Yaakov was well aware who the angel was seeing he had been sent to him specifically.
