David
Psalm 97:3BSB·traditional attribution

Fire goes before Him and consumes His foes on every side.

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

A fire goeth before him. Like an advance guard clearing the way. So was it at Sinai, so must it be: the very Being of God is power, consuming all opposition; omnipotence is a devouring flame which burneth up his enemies round about. God is longsuffering, but when he comes forth to judgment he will make short work with the unrighteous, they will be as chaff before the flame.

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.
