Psalm 103:20BSB·traditional attribution

Bless the LORD, all His angels mighty in strength who carry out His word, who hearken to the voice of His command.

John Calvin Reformed @genevareformer

PSALM 103 By this psalm every godly man is taught to give thanks to God for the mercies bestowed upon himself in particular, and then for the grace which God has vouchsafed to all his chosen ones in common, by making a covenant of salvation with them in his law, that he might make them partakers of his adoption.

Bess the Lord, ye his angels, that excel in strength. Finding his work of praise growing upon his hands, he calls upon "the firstborn sons of light" to speak the praises of the Lord, as well they may, for as Milton says, they best can tell.

Matthew Henry Presbyterian @wholebiblehenry

Here is, I. The doctrine of universal providence laid down, Psa 103:19. He has secured the happiness of his peculiar people by promise and covenant, but the order of mankind, and the world in general, he secures by common providence. The Lord has a throne of his own, a throne of glory, a throne of government.
