And he said unto him, what is thy name?.... Which question is put, not as being ignorant of it, but in order to take occasion from it, and the change of it, to show that he had granted his request, and had blessed him, and would yet more and more:
and he said, Jacob; the name given him at his birth, and by which he had always been called, and therefore tells it him at once, not staying to ask the reason of the question.

What is thy name? - Jacob (saith he) a supplanter, so Jacob signifies. Well, (faith the angel) be thou never so called any more: thou shalt be called Israel, a prince with God. He is a prince indeed, that is a prince with God; and those are truly honourable that are mighty, in prayer. Yet this was not all; having, power with God, he shall have power with men too; having prevailed for a blessing from heaven, he shall, no doubt, prevail for Esau's favour. Whatever enemies we have, if we can but make God our friend, we are well enough; they that by faith have power in heaven, have thereby as much power on earth as they have occasion for.
