Moses
Psalm 149:2BSB·traditional attribution

Let Israel rejoice in their Maker; let the children of Zion rejoice in their King.

John Calvin Reformed @genevareformer

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.

C.H. Spurgeon Reformed Baptist @princeofpreachers

Let Israel rejoice in him that made him. Here is that new creation which calls for the new song. It was Jehovah who made Israel to be Israel, and the tribes to become a great nation: therefore let the Founder of the nation be had in perpetual honour. Joy and rejoicing are evidently to be the special characteristics of the new song.

Matthew Henry Presbyterian @wholebiblehenry

We have here, I. The calls given to God's Israel to praise. All his works were, in the foregoing psalm, excited to praise him; but here his saints in a particular manner are required to bless him. Observe then, 1. Who are called upon to praise God.
