For the terrible one, &c.— The terrible and fierce were such as Herod Agrippa, who persecuted the apostles; the scorners and blasphemous, such as those who reproached the apostles when filled with the Spirit, as being drunk with wine. The watchers for iniquity, or of iniquity were such as those priests and scribes, who consulted together to take Jesus by subtilty: they who make a man an offender for a word, such as those who condemned Stephen for certain words imputed to him: those who lay a snare for him that reproveth in the gate, such as those who laid wait for Paul, after he had so fully reproved and baffled them; and lastly, they who overturn the just for a thing of nought, for no cause, were such as they who put to death James the less, surnamed the Just, and others of the first Christians, against whom they could lay no just cause of offence. See Vitringa.

20 For the terrible one is brought to nought, and the scorner is consumed, and all that watch for iniquity are cut off:
21 That make a man an offender for a word, and lay a snare for him that reproveth in the gate, and turn aside the just for a thing of nought.
