Ezekiel 21:9

“Son of man, prophesy and say, thus saith the Lord, &c.] Deliver out the following prophecy in the name of the Lord: say, a sword, a sword is sharpened, and also furbished; it is not only drawn out of its sheath, as before, but is made sharp and bright, and ready for use. It is repeated, either to show the certainty of it, or to express the terror and anguish of mind on account of it; persons in distress generally repeating that which is the occasion of it. The Targum interprets it of two swords, the sword of the Babylonians, and the sword of the Ammonites; first the one was to be used, and then the other: this latter, Jarchi and Kimchi observe, was fulfilled by Ishmael the son of Nethaniah…”

“sword--namely, of God (Deu 32:41). The Chaldeans are His instrument.”

“The second word of judgment: the glittering and destroying sword. The passage may be called the “Lay of the Sword;” it is written in the form of Hebrew poetry, with its characteristic parallelism. Ezekiel 21:10 It contemneth the rod of my son, as every tree - The rod is the scepter of dominion, assigned to Judah Genesis 49:10. The destroying sword of Babylon despises the scepter of Judah; it despises every tree. Others render the verse, “Shall we make mirth” (saying), “the rod of my son,” (the rod which corrects my people) “contemneth” (treats with scorn, utterly confounds) “every tree” (every other nation); or, the scepter of my people “contemneth” (proudly despises) every other nation.…”

“Furbished - Made clean and bright. Ezekiel 21:10”

“A sword: Eze 21:3, Eze 21:15, Eze 21:28; Deu 32:41, Deu 32:42; Job 20:25; Isa 66:16; Jer 12:12, Jer 15:2; Amo 9:4 sharpened: Psa 7:11-13; Isa 27:1, Isa 34:5, Isa 34:6 Ezekiel 21:10”
