Luke 1:16

And many of the children of Israel,.... To whom only, or at least chiefly, he was sent, and came preaching, and administering the ordinance of baptism; and great multitudes of them flocked unto him, attended on his ministry, believed in his doctrine, and submitted to his baptism, but not all; for some slighted his preaching, and rejected his baptism: however, some there were, and many too, that were converted under his ministry, confessed their sins, and were baptized by him; which verified this prediction:shall he turn to the Lord their God; not Jehovah, the Father; for though he was the Lord God of the Jews in general, and of those that were turned by John's ministry in a special manner; yet John cannot be said "to go before him", as he is in the next verse; but the Messiah is here meant, who is the Lord Jehovah, and is often so called in the Old Testament; particularly in a prophecy afterwards respected, Isa 40:3 a name peculiar to God alone: and who also is called God, as he is frequently with additional epithets; as the mighty God, God over all, the great God, the true God, and eternal life; and our, your, and their God, the God of his covenant people, whether Jews or Gentiles; see Isa 25:9.
