shall be no more called Jacob
Both names are applied to the nation descended from Jacob. When used characteristically "Jacob" is the name for the natural posterity of Abraham, Isaac, and Jacob; "Israel" for the spiritual part of the nation. See Isaiah 9:8. The "word" was sent to all the people, "Jacob," but it "lighted upon Israel," i.e. was comprehended by the spiritual part of the people. See "Israel" Genesis 12:2,3.
