Charles Ellicott Commentary Psalms 149:9

"To execute upon them the judgment written: This honor have all his saints. Praise ye Jehovah." — Psalms 149:9 (ASV)

The judgment written.—If we knew the exact circumstance that produced the psalm, and had the names of the nobles and princes taken prisoners, we would easily guess the contents of the “judgment written,” which was, perhaps, some special order, the execution of which is celebrated here; or we may think of the judgments against nations registered here and there in the sacred books, and thus established as authoritative, such as those against the Canaanites, Amalekites, and others; or we may give the phrase a still more general sense, as Isaiah 65:6 states: Behold, it is written before me: I will not keep silence, but will recompense, even recompense into their bosom. Should we not, however, read the verse: To execute judgment upon them. It is written, This honour have all his saints?

This honour.—Israel is here regarded as the instrument of God’s righteous judgments on the nations.
