Then said he to the multitude,.... That is, John, as the Ethiopic version reads; and the multitude to whom he spake the following words, were many of the Pharisees and Sadducees, as appears from Mat 3:7 That came forth to be baptized of him; who came out of their houses, towns, and cities, round about, to the place where John was; and hearing and seeing what he was about, desired to be admitted to his baptism: not that they "were baptised of him"; as the Arabic version renders it; but they came with a view of being baptized, were it thought fit and proper they should: but John refused them, saying to them, O generation of vipers, who hath warned you to flee from the wrath to come? See Gill on Mat 3:7.
