1:7-13 God's day is at hand; the punishment of presumptuous sinners is a sacrifice to the justice of God. The Jewish royal family shall be reckoned with for their pride and vanity; and those that leap on the threshold, invading their neighbours' rights, and seizing their possessions. The trading people and the rich merchants are called to account. Secure and careless people are reckoned with. They are secure and easy; they say in their heart, the Lord will not do good, neither will he do evil; that is, they deny his dispensing rewards and punishments. But in the day of the Lord's judgment, it will clearly appear that those who perish, fall a sacrifice to Divine justice for breaking God's law, and because they have no interest by faith in the Redeemer's atoning sacrifice.

7. Hold thy peace at the presence of the Lord—(Hab 2:20). Let the earth be silent at His approach [Maurer]. Or, "Thou whosoever hast been wont to speak against God, as if He had no care about earthly affairs, cease thy murmurs and self-justifications; submit thyself to God, and repent in time" [Calvin].

Lord … prepared a sacrifice—namely, a slaughter of the guilty Jews, the victims due to His justice (Isa 34:6; Jer 46:10; Eze 39:17).

bid his guests—literally, "sanctified His called ones" (compare Isa 13:3). It enhances the bitterness of the judgment that the heathen Chaldeans should be sanctified, or consecrated as it were, by God as His priests, and be called to eat the flesh of the elect people; as on feast days the priests used to feast among themselves on the remains of the sacrifices [Calvin]. English Version takes it not of the priests, but the guests bidden, who also had to "sanctify" or purify themselves before coming to the sacrificial feast (1Sa 9:13, 22; 16:5). Nebuchadnezzar was bidden to come to take vengeance on guilty Jerusalem (Jer 25:9).
