Psalms 149:6

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

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

Let the high praises of God be in their mouth, and a twoedged 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;

Do read the surrounding verses too, because the context often says more than a single verse.
