Charles Ellicott Commentary Isaiah 49:3

"and he said unto me, Thou art my servant; Israel, in whom I will be glorified." — Isaiah 49:3 (ASV)

You are my servant, O Israel. —Not that the “Servant” is merely the nation, but that he fulfills its ideal. “Israel” had begun with being an individual name. It should be so once more in the person of Him who would be truly “a prince with God.”

In whom I will be glorified. —Better, in whom I will glorify myself. The words find a conscious echo in John 13:31-32; John 17:1–5.
