For the Day of the Lord is at hand - Zephaniah, as is his custom, grounds this summons, which he had renewed from Habakkuk, to hushed silence before God, on Joel's prophetic warning , to show that it was not yet exhausted. A day of the Lord, of which Joel warned, had come and was gone; but it was only the herald of many such days; judgments in time, heralds and earnests, and, in their degree, pictures of the last which shall end time.

Dionysius: "All time is God's, since He Alone is the Lord of time; yet that is specially said to be His time when He doth anything special. Whence He saith, "My time is not yet come" John 7:6; whereas all time is His." The Day of the Lord is, in the first instance, Jerome: "the day of captivity and vengeance on the sinful people," as a forerunner of the Day of Judgment, or the day of death to each, for this too is near, since, compared to eternity, all the time of this world is brief.

For the Lord hath prepared a sacrifice - God had rejected sacrifices, offered amid unrepented sin; they were "an abomination to Him" Isaiah 1:11-15. When man will not repent and offer himself as "a living sacrifice, holy and acceptable to God" Romans 12:1, God, at last, rejects all other outward oblations, and the sinner himself is the sacrifice and victim of his own sins. The image was probably suggested by Isaiah's words, "The Lord hath a sacrifice in Bozrah, and a great slaughter in the land of Idumea" Isaiah 34:6; and Jeremiah subsequently uses it of the overthrow of Pharaoh at the Euphrates, "This is the day of the Lord of Hosts; that He may avenge Him of His adversaries, for the Lord God hath a sacrifice in the north country by the river Euphrates" Jeremiah 46:10. "The Lord hath made all things for Himself, yea even the wicked for the day of evil" Proverbs 16:4. All must honor God, either fulfilling the will of God and the end of their own being and of His love for them, by obeying that loving will with their own freewill, or, if they repudiate it to the end, by suffering it.

He hath bid His guests - (Literally, sanctified) God had before, by Isaiah, called the pagan whom He employed to punish Babylon, "My sanctified ones" Isaiah 13:3. Zephaniah, by giving the title to God's instruments against Judah, declares that themselves, having become in deeds like the pagan, were as pagan to Him. The instruments of His displeasure, not they, were so far his chosen, His called. Jeremiah repeats the saying, "Thus saith the Lord against the house of the king of Judah;...I have sanctified against thee destroyers, a man and his weapons" Jeremiah 22:6-7. That is, so far, a holy war in the purpose of God, which fulfills His will; from where Nebuchadnezzar was "His servant" Jeremiah 25:9, avenging His wrongs . Cyril: "To be sanctified, here denotes not the laying aside of iniquity, nor the participation of the Holy Spirit, but, as it were, to be foreordained and chosen to the fulfillment of this end." That is in a manner hallowed, which is employed by God for a holy end, though the instrument, its purposes, its aims, its passions, be in themselves unholy. There is an awe about "the scourges of God." As with the lightning and the tornado, there is a certain presence of God with them, in that through them His Righteousness is seen; although they themselves have as little of God as the "wind and storm" which "fulfill His word." Those who were once admitted to make offerings to God make themselves sacrifices to His wrath; these, still pagan and ungodly and in all besides reprobate, are His priests, because in this, although without their will, they do His will.

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).

"let all the wicked of the earth perish from before the Lord God:''

for the day of the Lord is at hand; the time of his vengeance on the Jewish nation for their sins, which he had fixed in his mind, and had given notice of by his prophets: this began to take place at Josiah's death, after which the Jews enjoyed little peace and prosperity; and his successor reigned but three months, was deposed by the king of Egypt, and carried thither captive, and there died; and Jehoiakim, that succeeded him, in the fourth year of his reign was carried captive into Babylon, or died by the way thither; so that this day might well be said to be at hand:

for the Lord hath prepared a sacrifice: his people the Jews, who were to fall a victim to his vengeance, and a sacrifice to his justice, to atone in some measure for the injury done to it by their sins; thus they that had offered sacrifice to idols, and neglected the sacrifices of the Lord, and especially the great sacrifice of Christ typified by them, the only proper atoning one, should themselves become a sacrifice to the just resentment of God; this he had prepared in his mind, determined should be done, and would bring about in his providence; see Isaiah 34:6,

he hath bid his guests: or "called ones" (o); the Chaldeans, whom he invited and called to this sacrifice and feast: or whom he "prepared", or "sanctified" (p); he prepared them in his purpose and providence; he set them apart for this service, and called them to it; to be the sacrificers of this people, and to feast upon them; to spoil them of their goods and riches, and enjoy them. These guests may also design, as Kimchi observes, the fowls of the heaven, and the beasts of the field, invited to feast upon the slain; see Ezekiel 39:17.
