David
Psalm 89:11ESV·traditional attribution

The heavens are yours; the earth also is yours; the world and all that is in it, you have founded them.

John Calvin Reformed @genevareformer

PSALM 89 The prophet who wrote this psalm, whoever he was, in approaching the throne of grace to make supplication to God in behalf of the afflicted Church, lays down, as an encouragement both to himself and the rest of the faithful to cherish good hope, the covenant which God had made with David.

C.H. Spurgeon Reformed Baptist @princeofpreachers

The heavens are thine, the earth also is thine. All things are alike God's—rebellious earth as well as adoring heaven. Let us not despair of the kingdom of truth; the Lord has not abdicated the throne of earth or handed it over to the sway of Satan. As for the world and the fulness thereof, thou hast founded them.

Matthew Henry Presbyterian @wholebiblehenry

These verses are full of the praises of God. Observe, I. Where, and by whom, God is to be praised. 1. God is praised by the angels above: The heavens shall praise thy wonders, O Lord! Psa 89:5; that is, "the glorious inhabitants of the upper world continually celebrate thy praises." Bless the Lord, you his angels, Psa 103:20.
