Psalm 149 Psalm 149 Psalm 149 is the 149th psalm of the Book of Psalms, a hymn as the book's penultimate piece. The first verse of the psalm calls to praise in singing, "Sing a new song unto the Lord". Similar to Psalm 96 and Psalm 98 (Cantate Domino), Psalm 149 calls to praise God in music and dance, because he has chosen his people and helped them to victory. Psalm 149 also calls to be ready to fight. The psalm is a regular part of Jewish, Catholic, and Anglican liturgies. It has been set to music often, notably by Antonín Dvořák
