21:1-17 Here is an explanation of the parable in the last chapter. It is declared that the Lord was about to cut off Jerusalem and the whole land, that all might know it was his decree against a wicked and rebellious people. It behoves those who denounce the awful wrath of God against sinners, to show that they do not desire the woful day. The example of Christ teaches us to lament over those whose ruin we declare. Whatever instruments God uses in executing his judgments, he will strengthen them according to the service they are employed in. The sword glitters to the terror of those against whom it is drawn. It is a sword to others, a rod to the people of the Lord. God is in earnest in pronouncing this sentence, and the prophet must show himself in earnest in publishing it.Son of man, prophesy and say, thus saith the Lord,.... 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 slaying Gedaliah, sent for that purpose by Baalis king of the Ammonites, Jeremiah 40:14, but if two distinct swords are meant, I should rather think the sword of the Chaldeans, and the sword of the Romans, are intended. Cocceius, before observed, interprets it only of the latter; but Abendana both of the sword of the king of Babylon, and of the sword of the Romans.
