C. F. Keil and Franz Delitzsch on Genesis 27:18-23

Gen 27:18-23

But Jacob had no easy task to perform before his father. As soon as he had spoken on entering, his father asked him, “Who art thou, my son?” On his replying, “I am Esau, thy first-born,” the father expressed his surprise at the rapid success of his hunting; and when he was satisfied with the reply, “Jehovah thy God sent it (the thing desired) to meet me,” he became suspicious about the voice, and bade him come nearer, that he might feel him. But as his hands appeared hairy like Esau’s, he did not recognise him; and “so he blessed him.” In this remark (Gen 27:23) the writer gives the result of Jacob’s attempt; so that the blessing is merely mentioned proleptically here, and refers to the formal blessing described afterwards, and not to the first greeting and salutation.
