David
Psalm 97:4ESV·traditional attribution

His lightnings light up the world; the earth sees and trembles.

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

His lightnings enlightened the world. In times of tempest the whole of nature is lighted up with a lurid glare, even the light of the sun itself seems dim compared with the blaze of lightning. If such are the common lights of nature what must be the glories of the Godhead itself?

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.
