Charles Ellicott Commentary Isaiah 48:12

"Hearken unto me, O Jacob, and Israel my called: I am he; I am the first, I also am the last." — Isaiah 48:12 (ASV)

Hearken unto me, O Jacob. —The prophet is drawing near to the end of the first great section of his book, and his conclusion takes the form of a condensed epitome of the great argument of Isaiah 40-47, asserting the oneness, the eternity, the omnipotence, the omniscience of Jehovah.
