Matthew Henry Commentary Psalms 149:6-9

"[Let] the high praises of God [be] in their mouth, And a two-edged sword in their hand; To execute vengeance upon the nations, And punishments upon the peoples; To bind their kings with chains, And their nobles with fetters of iron; To execute upon them the judgment written: This honor have all his saints. Praise ye Jehovah." — Psalms 149:6-9 (ASV)

Some of God's servants in the past were appointed to execute vengeance according to His word. They did not do it from personal revenge or earthly politics, but in obedience to God's command. And the honor intended for all the saints of God consists of their triumphs over the enemies of their salvation. Christ never intended His gospel to be spread by fire and sword, or His righteousness by the wrath of man.

But let the high praises of God be in our mouths, while we wield the sword of the Word of God, with the shield of faith, in warfare with the world, the flesh, and the devil. The saints shall be more than conquerors over the enemies of their souls, through the blood of the Lamb and the word of His testimony. The completion of this will be in the judgment of the great day.

Then judgment shall be executed. Behold Jesus and His gospel church, chiefly in her millennial state. He and His people rejoice in each other; by their prayers and efforts they work with Him, while He goes forth in the chariots of salvation, conquering sinners by grace, or in chariots of vengeance, to destroy His enemies.
