God was about to appear in wrath against them, and it is a fearful thing to fall into his hands: The day of the Lord is at hand (v. 6), a little day of judgment, when God will act as a just avenger of his own and his people's injured cause. And there are those who will have reason to tremble when that day is at hand. The day of the Lord cometh, v. 9. Men have their day now, and they think to carry the day; but God laughs at them, for he sees that his day is coming, Ps. xxxvii. 13.

God will deal in severity with them for the severities they exercised upon God's people; with the froward, with the cruel, he will show himself froward, will show himself cruel, and give the blood-thirsty blood to drink.
