David
Psalm 78:69ESV·traditional attribution

He built his sanctuary like the high heavens, like the earth, which he has founded forever.

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 he built his sanctuary like high palaces. The tabernacle was placed on high, literally and spiritually it was a mountain of beauty. True religion was exalted in the land. For sanctity it was a temple, for majesty it was a palace. Like the earth which he hath established for ever. Stability was well as stateliness were seen in the temple, and so also in the church of God.

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.
