3:8-13 The preaching of the gospel is predicted, when vengeance would be executed on the Jewish nation. The purifying doctrines of the gospel, or the pure language of the grace of the Lord, would teach men to use the language of humility, repentance, and faith. Purity and piety in common conversation is good. The pure and happy state of the church in the latter days seems intended. The Lord will shut out boasting, and leave men nothing to glory in, save the Lord Jesus, as made of God to them wisdom, righteousness, sanctification, and redemption. Humiliation for sin, and obligations to the Redeemer, will make true believers upright and sincere, whatever may be the case among mere professors.

8. wait ye upon me—Here Jehovah turns to the pious Jews. Amidst all these judgments on the Jewish nation, look forward to the glorious time of restoration to be ushered in by God's precious outpouring of wrath on all nations, Isa 30:18-33; where the same phrase, "blessed are all they that wait for Him," is used as to the same great event. Calvin erroneously makes this verse an address to the ungodly; and so Maurer, "Ye shall not have to wait for Me in vain"; I will presently come armed with indignation: I will no longer contend with you by My prophets.

until the day—that is, waiting for the day (Hab 2:3).

rise up to the prey—like a savage beast rising from his lair, greedy for the prey (compare Mt 24:28). Or rather, as a warrior leading Israel to certain victory, which is expressed by "the prey," or booty, which is the reward of victory. The Septuagint and Syriac versions read the Hebrew, "I rise up as a witness" (compare Job 16:8; Mal 3:5). Jehovah being in this view witness, accuser, and judge. English Version is better (compare Isa 33:23).

gather the nations—against Jerusalem (Zec 14:2), to pour out His indignation upon them there (Joe 3:2; Zec 12:2, 3).
