“And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.”
King James Version (KJV)
19:15 And he shall rule them - Who are not slain by his sword. With a rod of iron - That is, if they will not submit to his golden sceptre. And he treadeth the wine press of the wrath of God - That is, he executes his judgments on the ungodly. This ruler of the nations was born (or appeared as such) immediately after the seventh angel began to sound. He now appears, not as a child, but as a victorious warrior. The nations have long ago felt his iron rod, partly while the heathen Romans, after their savage persecution of the Christians, themselves groaned under numberless plagues and calamities, by his righteous vengeance; partly, while other heathens have been broken in pieces by those who bore the Christian name. For although the cruelty, for example, of the Spaniards in America, was unrighteous and detestable, yet did God therein execute his righteous judgment on the unbelieving nations; but they shall experience his iron rod as they never did yet, and then will they all return to their rightful Lord.
Re 19:15 Out of his mouth goeth a sharp sword. See PNT "Re 1:16". This symbolizes the word by which he achieved his conquests. And he shall rule them with a rod of iron. See notes on Re 2:27 12:5 This implies not a stern, but a firm and lasting rule. He treadeth the winepress of the fierceness and wrath of Almighty God. He shall inflict God's judgments on the sins of the earth. See notes on Re 14:17-19.
