May the high praises of God be in their mouths, and a double-edged sword in their hands,
PSALM 149 If we may be allowed to compare this Psalm with the former ones, and the next, which is the last, the only difference is, that while the author of the Psalm, whoever he was, has hitherto spoken of God’s special care and protection of his Church in connection with the common providential government of the world, here he speaks of his benefits to the Church exclusively.
Commenting on Psalm 149:1-9
Let the high praises of God be in their mouth, and a two edged sword in their hand. It seems they are not always on their beds, but are ready for deeds of prowess. When called to fight, the meek are very hard to overcome; they are just as steady in conflict as they are steadfast in patience.
The Israel of God are here represented triumphing over their enemies, which is both the matter of their praise (let them give to God the glory of those triumphs) and the recompence of their praise; those that are truly thankful to God for their tranquillity shall be blessed with victory.
