David
Psalm 110:6ESV·traditional attribution

He will execute judgment among the nations, filling them with corpses; he will shatter chiefs over the wide earth.

John Calvin Reformed @genevareformer

PSALM 110 In this psalm David sets forth the perpetuity of Christ’s reign, and the eternity of his priesthood; and, in the first place, he affirms, That God conferred upon Christ supreme dominion, combined with invincible power, with which he either conquers all his enemies, or compels them to submit to him.

C.H. Spurgeon Reformed Baptist @princeofpreachers

He shall judge among the heathen, or, among the nations. All nations shall feel his power, and either yield to it joyfully or be crushed before it. He shall fill the places with the dead bodies. In the terrible battles of his gospel all opponents shall fall till the field of fight is heaped high with the slain.

Matthew Henry Presbyterian @wholebiblehenry

Here we have our great Redeemer, I. Conquering his enemies (Psa 110:5, Psa 110:6) in order to the making of them his footstool, Psa 110:1. Our Lord Jesus will certainly bring to nought all the opposition made to his kingdom, and bring to ruin all those who make that opposition and persist in it.
