David
Psalm 95:3ESV·traditional attribution

For the LORD is a great God, and a great King above all gods.

John Calvin Reformed @genevareformer

PSALM 95 The inspired penman of this psalm, whoever he was, This psalm has no inscription, but the Septuagint, Vulgate, Æthiopic, Arabic, and Syriac versions, and the apostle Paul in Hebrews 4:7, ascribe it to David; so that there can be no doubt that it is one of the compositions of the sweet singer of Israel.

C.H. Spurgeon Reformed Baptist @princeofpreachers

For the Lord is a great God, and a great King above all gods. No doubt the surrounding nations imagined Jehovah to be a merely local deity, the god of a small nation, and therefore one of the inferior deities; the psalmist utterly repudiates such an idea.

Matthew Henry Presbyterian @wholebiblehenry

The psalmist here, as often elsewhere, stirs up himself and others to praise God; for it is a duty which ought to be performed with the most lively affections, and which we have great need to be excited to, being very often backward to it and cold in it. Observe, I. How God is to be praised. 1. With holy joy and delight in him.
