David
Psalm 68:2ESV·traditional attribution

As smoke is driven away, so you shall drive them away; as wax melts before fire, so the wicked shall perish before God!

John Calvin Reformed @genevareformer

PSALM 68 In this psalm it was David’s design to celebrate the victories which, through the blessing of God, he had gained over his enemies; As to the time and occasion of the composition of this psalm, the majority of interpreters refer it to the translation of the ark from the house of Obed-Edom to Mount Zion, and with this every part of it would, no doubt, harmonize.

C.H. Spurgeon Reformed Baptist @princeofpreachers

As smoke is driven away. Easily the wind chases the smoke, completely it removes it, no trace is left; so, Lord, do thou to the foes of thy people. They fume in pride, they darken the sky with their malice, they mount higher and higher in arrogance, they defile wherever they prevail.

Matthew Henry Presbyterian @wholebiblehenry

In these verses, I. David prays that God would appear in his glory, 1. For the confusion of his enemies (Psa 68:1, Psa 68:2): "Let God arise, as a judge to pass sentence upon them, as a general to take the field and do execution upon them; and let them be scattered, and flee before him, as unable to keep their ground, much less to make head against him.
