It is interesting to notice the way in which the titles "Jacob" and "Israel" are introduced in the close of the book of Genesis; as, for example, "One told Jacob, and said, Behold, thy son Joseph cometh unto thee: and Israel strengthened himself, and sat upon the bed." Then, it is immediately added, "And Jacob said unto Joseph, God Almighty appeared unto me at Luz." Now, we know, there is nothing in Scripture without its specific meaning, and hence this interchange of names contains some instruction. In general, it may be remarked that "Jacob" sets forth the depth to which God has descended—"Israel," the height to which Jacob was raised.
