1:4 Yahweh announced that He would stretch out His hand in judgment against Judah and the people of Jerusalem. Stretching out the hand is a figure of speech that implies a special work of punishment (cf. Exod. 6:6; Deut. 4:34; 2 Kings 17:36; Isa. 14:26-27; Jer. 27:5; 32:17; et al.). He promised to cut off the remnant of Baal worshippers who remained in Judah as well as the priests of Baal and the unfaithful priests of Yahweh. He would also terminate their reputations and memories (cf. 2 Kings 23:5; Hos. 10:5).
This reference has suggested to some interpreters that Zephaniah wrote after Josiah began his reforms since Josiah revived the worship of Yahweh and tried unsuccessfully to eliminate idolatry (2 Chron. 34:4). However, this verse may simply mean that the Lord would judge the idolaters in Judah, "Baal"being a figure (synecdoche) for all idolatry.
1:5 The Lord would also judge those who worshipped the sun, moon, stars, and planets, which the idolatrous Israelites did on their flat housetops (cf. Deut. 4:19; 2 Kings 21:3, 5; 23:4-5; Jer. 19:13). He would also punish the Judeans who worshipped both Yahweh and the pagan gods of the nations (cf. 2 Kings 16:3; 21:6; Jer. 32:35). "Milcom,"(Molech, the god of Ammon; 1 Kings 11:33), probably represents all foreign gods. Swearing to and by a deity meant pronouncing an oath that called on that god to punish the oath-taker if he or she failed to do what he or she promised.
1:6 Judgment would come, too, on all God's people who had apostatized, namely, departed from loving and following Yahweh, and had stopped praying to Him. They might not have participated in pagan idolatry, but if their love had grown cold, they were still guilty (cf. Rev. 2:1-7). The Lord commanded His people to love Him wholeheartedly (cf. Deut. 6:5). They may have forgotten Him, but He had not forgotten them.
"Sometimes it is the apathetic and indifferent who are more responsible for a nation's moral collapse than those who are actively engaged in evil, or those who have failed in the responsibilities of leadership."15
In this pericope the prophet identified three types of idolatry: "the overtly pagan, the syncretistic, and the religiously indifferent."16Practitioners of all three would draw punishment from Yahweh.
How does this promise to judge the Israelites harmonize with the earlier prophecy that God would destroy the whole earth (vv. 2-3)? This is an example of a prophet's foreshortened view of the future in which he could not see the difference in time between some events that he predicted and others (cf. Isa. 61:1-3; Dan. 11:35-36; et al.). God judged Israel when the Babylonians overran Judah and destroyed Jerusalem in 586 B.C. He will also judge the Israelites in the Tribulation (cf. Jer. 30:7; Rev. 6-18; et al.). Zephaniah described God's judgment of the people of Judah without specifying exactly when He would judge them. Most of what Zephaniah prophesied in this pericope found fulfillment, at least initially, in 586 B.C.
