Psalm 149:6-9 King James-6 Let the high praises of God be in their mouth, and a two-edged sword in their hand;7 To execute vengeance upon the heathen, and punishments upon the people;8 To bind their kings with chains, and their nobles with fetters of iron; 9 To execute upon them the judgment written: this honor have all his saints. Praise ye the Lord.
