O ye seed of Abraham his servant,.... These are the persons all along before addressed; the Israelites, who descended from Abraham, were his natural seed and offspring, and who had reason to give thanks unto the Lord and praise his name, since so many and such wonderful things had been done for them; though all that were his natural seed were not the children of God; and such who have the same faith he had, and tread in the steps he did, are Christ's, and partakers of his grace; these are Abraham's seed, and heirs according to the promise; and are under the greatest obligations to praise the Lord.
Abraham is here called his servant, as also in Ps 105:42, being a true worshipper of God; though sometimes his friend, which is not inconsistent; though this character, according to the Septuagint, Vulgate Latin, and all the Oriental versions, belongs to his seed, they rendering it in the plural, "his servants".
It follows,ye children of Jacob his chosen; this is added to distinguish the persons intended from the other seed of Abraham in the line of Ishmael; for in Isaac his seed was called, which were the children of the promise, and that in the line of Jacob, and not in the line of Esau; from whom they were called Israel or Israelites, a people whom the Lord chose above all people on the face of the earth; for the word "chosen" may be connected with the children as well as with Jacob.
