Psalm 149:5

3Let them praise his name in the dance: let them sing praises unto him with the timbrel and harp.

4For the LORD taketh pleasure in his people: he will beautify the meek with salvation.

5Let the saints be joyful in glory: let them sing aloud upon their beds.

6Let the high praises of God be in their mouth, and a two-edged sword in their hand;

7To execute vengeance upon the heathen, and punishments upon the people;
