Psalm 149

1 Praise the Lord! Sing to the Lord a new song and His praise in the assembly of saints.
2 Let Israel rejoice in their maker. Let the children of Zion be joyful in their king.
3 Let them praise his name with the dance let them sing praises to him with the timbrel and harp.
4 For the Lord takes pleasure in His people; He will beautify the humble with salvation.
5 Let the saints be joyful in glory; let them sing aloud on their beds.
6 Let the high praises of God be in their mouth and a two-edged sword in their hand,
7 to execute vengeance on the nations, and punishment on the peoples;
8 to bind their kings with chains, their nobles with fetters of iron;
9 to execute on them the written judgment – this honor have all the saints. Praise the Lord!

I don’t know about you, but this idea of the saints being ‘honored’ to act in vengeance...
