The prophet exhorteth to praise God for his love to the Church,
Psalms 149:1 Praise ye the LORD. Sing unto the LORD a new song, and his praise in the assembly of the 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 unto 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 exult in glory: let them sing for joy 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 nations, and punishments upon the peoples; Psalms 149:8 To bind their king's with chains, and their nobles with fetters of iron; Psalms 149:9 To execute upon them the judgment written: this honour have all his saints. Praise ye the LORD.
