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.Seeing then that I will cut off from thee the righteous and the wicked,.... Some by the sword, some by famine, some by pestilence, and others by captivity; and, upon the whole, none spared, but the land left desolate:

therefore shall my sword go forth out of his sheath against all flesh, from the south to the north; the Chaldean army shall go out of their own land against all the inhabitants of Judea, from Beersheba to Dan; this explains what is meant by all faces being burnt from the south to the north, Ezekiel 20:47, namely, the general destruction of the Jews by the Chaldeans.
