Psalms 110:5

“The Lord at thy right hand - See the notes at Psalms 16:8. Shall strike through kings - The Hebrew word here rendered “shall strike,” - from מחץ mâchats - means “to shake, to agitate”; and then, “to shake in pieces, to dash in pieces, to crush”; and here it has the sense of dashing in pieces, smiting, wounding, crushing. The “kings” referred to are the enemies of God and the Messiah, and the idea is that all would be subdued before him; that he would set up a universal dominion; that none would be able to stand before him; or, that he would reign over all the earth. The “language” is that which is derived from conquests in war; from the subjugation of enemies by force of arms. Compare the…”

“The Lord - God the son; the Lord, who is at thy right - hand. Strike - Shall destroy all those kings who are obstinate enemies to him. Psalms 110:6”

“110:5-7 The new priestly role of David’s descendant does not rescind his old role as conquering ruler. He must still bring the nations under his rule (110:2-3; see Ps 2). 110:5-6 at your right hand: This position brings help and protection (see 16:7-8; 108:13). • The Lord will strike down rebellious kings. Rebellion against the Lord is a capital offense (Ps 2; Rom 6:23).”

“at thy: Psa 110:1, Psa 16:8; Mar 16:19; Act 2:34-36, Act 7:55, Act 7:56 strike: Psa 2:2-6, Psa 2:9-12, Psa 45:4, Psa 45:5, Psa 68:14, Psa 68:30, Psa 149:7-9; Zac 9:9, Zac 9:10, Zac 9:13-15; Rev 17:12-14, Rev 19:11-21, Rev 20:8, Rev 20:9 in the day: Psa 21:8, Psa 21:9; Eze 38:18, Eze 38:19; Rom 2:5; Rev 6:15-17, Rev 11:18 Psalms 110:6”

“Just as in Psa 110:2 after Psa 110:1, so now here too after the divine utterance, the poet continues in a reflective strain. The Lord, says Psa 110:5, dashes in pieces kings at the right hand of this priest-king, in the day when His wrath is kindled ( Psa 2:12, cf. Psa 21:10). אדני is rightly accented as subject. The fact that the victorious work of the person addressed is not his own work, but the work of Jahve on his behalf and through him, harmonizes with Psa 110:1. The sitting of the exalted one at the right hand of Jahve denotes his uniform participation in His high dignity and dominion. But in the fact that the Lord, standing at his right hand (cf. the counterpart in Psa 109:6), helps…”
