David
Psalm 115:13BSB·traditional attribution

He will bless those who fear the LORD—small and great alike.

John Calvin Reformed @genevareformer

PSALM 115 It is obvious that this psalm was penned when the Church was deeply afflicted. Unworthy as they are to be heard by God, the faithful, nevertheless, offer up supplications to him for deliverance, lest his holy name might be exposed to scorn and reproach among the heathen.

C.H. Spurgeon Reformed Baptist @princeofpreachers

He will bless them that fear the Lord, both small and great. So long as a man fears the Lord it matters nothing whether he be prince or peasant, patriarch or pauper, God will assuredly bless him. He supplies the want of every living thing, from the leviathan of the sea to the insect upon a leaf, and he will suffer none of the godly...

Matthew Henry Presbyterian @wholebiblehenry

In these verses, I. We are earnestly exhorted, all of us, to repose our confidence in God, and not suffer our confidence in him to be shaken by the heathens' insulting over us upon the account of our present distresses.
