Albert Barnes Commentary Psalms 24:8

"Who is the King of glory? Jehovah strong and mighty, Jehovah mighty in battle." — Psalms 24:8 (ASV)

Who is this King of glory? This is probably the response of a portion of the choir of singers. The answer is found in the other part of the verse.

The Lord strong and mighty—Yahweh, strong and mighty—describing Him by His most exalted attributes as a God of power. This is in accordance with the idea in Psalm 24:1-2, where He is represented as the Creator and Proprietor of all the earth. Perhaps, also, there is an allusion to the fact that He is mighty, as distinguished from idols, which have no power.

The Lord mighty in battle—who displays His power eminently in overthrowing hostile armies; perhaps this alludes to the victories won when His people were animated in war by the presence of the ark in the midst of their armies, when the victory could be properly traced to the fact that the ark, the symbol of the divine presence, was with them, and when, therefore, the victory would be rightly ascribed to Yahweh Himself.
