Behold, the day of the LORD cometh, cruel both with wrath and fierce anger, to lay the land desolate: and he shall destroy the sinners thereof out of it.

Wesley's Notes

9. cruel-not strictly, but unsparingly just; opposed to mercy. Also answering to the cruelty (in the strict sense) of Babylon towards others (Isa 14:17) now about to be visited on itself.

the land-"the earth" [Horsley]. The language of Isa 13:9-13 can only primarily and partially apply to Babylon; fully and exhaustively, the judgments to come, hereafter, on the whole earth. Compare Isa 13:10 with Mt 24:29; Re 8:12. The sins of Babylon, arrogancy (Isa 13:11; Isa 14:11; 47:7, 8), cruelty, false worship (Jer 50:38), persecution of the people of God (Isa 47:6), are peculiarly characteristic of the Antichristian world of the latter days (Da 11:32-37; Re 17:3, 6; 18:6, 7, 9-14, 24).

Matthew Henry's Concise Commentary

13:6-18 We have here the terrible desolation of Babylon by the Medes and Persians. Those who in the day of their peace were proud, and haughty, and terrible, are quite dispirited when trouble comes. Their faces shall be scorched with the flame. All comfort and hope shall fail. The stars of heaven shall not give their light, the sun shall be darkened. Such expressions are often employed by the prophets, to describe the convulsions of governments. God will visit them for their iniquity, particularly the sin of pride, which brings men low. There shall be a general scene of horror. Those who join themselves to Babylon, must expect to share her plagues, Re 18:4. All that men have, they would give for their lives, but no man's riches shall be the ransom of his life. Pause here and wonder that men should be thus cruel and inhuman, and see how corrupt the nature of man is become. And that little infants thus suffer, which shows that there is an original guilt, by which life is forfeited as soon as it is begun. The day of the Lord will, indeed, be terrible with wrath and fierce anger, far beyond all here stated. Nor will there be any place for the sinner to flee to, or attempt an escape. But few act as though they believed these things.
