Moses
Psalm 97:5BSB·traditional attribution

The mountains melt like wax at the presence of the LORD, before the Lord of all the earth.

John Calvin Reformed @genevareformer

PSALM 97 The description which we have of the kingdom of God in this psalm, does not apply to the state of it under the Law. We may infer, accordingly, that it contains a prediction of that kingdom of Christ, which was erected upon the introduction of the Gospel.

C.H. Spurgeon Reformed Baptist @princeofpreachers

The hills melted like wax at the presence of the Lord. Inanimate nature knows its Creator, and worships him in its own fashion. States and kingdoms which stand out upon the world like mountains are utterly dissolved when he decrees their end. Systems as ancient and firmly rooted as the hills pass away when he does but look upon them.

Matthew Henry Presbyterian @wholebiblehenry

What was to be said among the heathen in the foregoing psalm (Psa 97:10) is here said again (Psa 97:1) and is made the subject of this psalm, and of psalm 99. The Lord reigns; that is the great truth here laid down. The Lord Jehovah reigns, he that made the world governs it; he that gave being gives motion and power, gives law and commission, gives success and event.
