David
Psalm 33:21BSB·traditional attribution

For our hearts rejoice in Him, since we trust in His holy name.

John Calvin Reformed @genevareformer

PSALM 33. David, or whoever was the author of this psalm, in order to excite believers to praise God, founds his argument upon the general providence of God, by which he sustains, protects, and governs the whole world. Afterwards he celebrates God’s paternal kindness towards his chosen people, showing at the same time how necessary it is that the godly should be cherished by his special care. Psalm 33:1-4 1.

C.H. Spurgeon Reformed Baptist @princeofpreachers

For our hearts shall rejoice in him. The duty commended and commanded in the first verse is here presented to the Lord. We, who trust, cannot but be of a glad heart, our inmost nature must triumph in our faithful God. Because we have trusted in his holy name. The root of faith in due time bears the flower of rejoicing. Doubts breed sorrow, confidence creates joy.

Matthew Henry Presbyterian @wholebiblehenry

We are here taught to give to God the glory, I. Of his common providence towards all the children of men. Though he has endued man with understanding and freedom of will, yet he reserves to himself the government of him, and even of those very faculties by which he is qualified to govern himself. 1.
