Matthew Poole and continuators on Isaiah 49:3

3. And said unto me; Thou art my servant, O Israel , in whom I will be glorified.

As the name of David is sometimes given to his Successors, 1 Kings 12. 16. and particularly to Christ, Ier. 30. 9. Ezek. 34. 23. Hos. 3. 5. and Iacob is called, as many think, by the name of his Grand-Father, Abraham, Act. 7. 16. and the name of Isaac is given to his Posterity, Amos 7. 9. So here the name of Israel may not unfitly be given to Christ, not onely because he descended from his Loins; but also because he was the true and the great Israel, who, in a more eminent manner, prevailed with God, as that Name signifies, of whom Iacob, who was first called Israel, was but a Type: And as the name of Christ, the Head is sometimes given to the Body, the Church, as 1 Cor. 12. 12. So it is not strange if, on the contrary, the name of Israel, which properly belongs to the Church, be given to Christ the Head of it. But this Word may be otherwise rendred, being joyned, Either 1. with the foregoing words, Thou art my servant, unto or in or for Israel, i. e. to bring them back unto me, from whom they have revolted: Or 2. with the following words; it is Israel, in whom I will glorify my self by thee.
