1:24 {12} And they which were sent were of the Pharisees.
(12) Christ is the author of baptism, and not John: and therefore the authority of this does not come from John, who is the minister, but wholly from Christ the Lord.
1:24 Were of the Pharisees. See PNT Mt 3:7.
1:24 They who were sent were of the Pharisees - Who were peculiarly tenacious of old customs, and jealous of any innovation (except those brought in by their own scribes) unless the innovator had unquestionable proofs of Divine authority.
1:19-28 John disowns himself to be the Christ, who was now expected and waited for. He came in the spirit and power of Elias, but he was not the person of Elias. John was not that Prophet whom Moses said the Lord would raise up to them of their brethren, like unto him. He was not such a prophet as they expected, who would rescue them from the Romans. He gave such an account of himself, as might excite and awaken them to hearken to him. He baptized the people with water as a profession of repentance, and as an outward sign of the spiritual blessings to be conferred on them by the Messiah, who was in the midst of them, though they knew him not, and to whom he was unworthy to render the meanest service.
