David
Psalm 78:72ESV·traditional attribution

With upright heart he shepherded them and guided them with his skillful hand.

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.

C.H. Spurgeon Reformed Baptist @princeofpreachers

So he fed them according to the integrity of his heart. David was upright before God, and never swerved in heart from the obedient worship of Jehovah. Whatever faults he had, he was unfeignedly sincere in his allegiance to Israel's superior king; he shepherded for God with honest heart. And guided them by the skilfulness of his hands.

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.
