Psalms 21:9

“Thou shalt make them as a fiery oven, etc.] Some think the allusion is to David’s causing the Ammonites to pass through the brick kiln, (<101231>2 Samuel 12:31); others to the burning of Sodom and Gomorrah: it represents what a severe punishment shall be inflicted on the enemies of Christ; they shall be cast into a fiery oven, or furnace of fire, as Shadrach, Meshach, and Abednego, were by the order of Nebuchadnezzar; so some render the words, “thou shalt put them into a fiery oven”, k, “as”, being put for b, “into” f323: wicked men are as dry trees, as stubble, as thorns or briers, and are fit fuel for a fiery oven or furnace; by which is meant the wrath and fury of God, which is poured…”

“The king is only God's agent. anger--literally, "face," as appearing against them. as a fiery oven--as in it.”

“Oven - Like wood, which when it is cast in there, is quickly consumed. Psalms 21:10”

“21:9 The flaming furnace and fire portray the severity of God’s judgment on the wicked. In the Old Testament, this image often refers to hell (11:6; 18:8; 50:3; 68:2; 78:21; 79:5; 80:16; 89:46; 97:3; 104:4; 140:10; see Isa 66:24).”

“(Heb.: 21:10-11) Hitherto the Psalm has moved uniformly in synonymous dipodia, now it becomes agitated; and one feels from its excitement that the foes of the king are also the people's foes. True as it is, as Hupfeld takes it, that לעת פּניך sounds like a direct address to Jahve, Psa 21:10 nevertheless as truly teaches us quite another rendering. The destructive effect, which in other passages is said to proceed from the face of Jahve, Psa 34:17; Lev 20:6; Lam 4:16 (cf. ἔχει θεὸς ἔκδικον ὄμμα), is here ascribed to the face, i.e., the personal appearing ( Sa2 17:11) of the king.
