The prophet exhorts to praise God for his love to the church;

149:1 Praise Yahweh!
Sing to Yahweh a new song,
his praise in the assembly of the saints.

149:2 Let Israel rejoice in him who made them.
Let the children of Zion be joyful in their King.

149:3 Let them praise his name in the dance!
Let them sing praises to him with tambourine and harp!

149:4 For Yahweh takes pleasure in his people.
He crowns the humble with salvation.

and for that power which he has given to the church.

149:5 Let the saints rejoice in honor.
Let them sing for joy on their beds.

149:6 May the high praises of God be in their mouths,
and a two-edged sword in their hand;

149:7 To execute vengeance on the nations,
and punishments on the peoples;

149:8 To bind their kings with chains,
and their nobles with fetters of iron;

149:9 to execute on them the written judgment.
All his saints have this honor.
Praise Yah!
