David
Psalm 78:61BSB·traditional attribution

He delivered His strength to captivity, and His splendor to the hand of the adversary.

John Calvin Reformed @genevareformer

PSALM 78 To comprehend many things within small compass, it is to be observed, that in this psalm there are two leading topics. On the one hand, it is declared how God adopted for himself a Church from the posterity of Abraham, how tenderly and graciously he cherished it, how wonderfully he brought it out of Egypt, and how varied were the blessings which he bestowed upon it.

And delivered his strength into captivity. The ark was captured by the Philistines in battle, only because the Lord for the punishment of Israel chose to deliver it into their hands, otherwise they could have had no power at all against it. The token of the divine presence is here poetically called "his strength; ", and, indeed, the presence of the Lord is his strength among his people.

Matthew Henry Presbyterian @wholebiblehenry

The matter and scope of this paragraph are the same with the former, showing what great mercies God had bestowed upon Israel, how provoking they had been, what judgments he had brought upon them for their sins, and yet how, in judgment, he remembered mercy at last.
