The prophet exhorteth to praise God for his love to the Church,
Psalms 149:1 Praise ye the LORD. Sing to the LORD a new song, [and] his praise in the congregation of saints. Psalms 149:2 Let Israel rejoice in him that made him: let the children of Zion be joyful in their King. Psalms 149:3 Let them praise his name in the dance: let them sing praises to him with the timbrel and harp: Psalms 149:4 For the LORD taketh pleasure in his people: he will beautify the meek with salvation.
and for that power which he hath given to the Church.
Psalms 149:5 Let the saints be joyful in glory: let them sing aloud upon their beds. Psalms 149:6 [Let] the high [praises] of God [be] in their mouth, and a two-edged sword in their hand; Psalms 149:7 To execute vengeance upon the heathen, [and] punishments upon the people; Psalms 149:8 To bind their kings with chains, and their nobles with fetters of iron; Psalms 149:9 To execute upon them the judgment written: this honor have all his saints. Praise ye the LORD.
