These verses continue the subject of judgment against Israel’s leadership (see 1:23–25). The removal of leadership at all levels would allow the mob to gain control. Chaos and famine would turn Judah and Jerusalem into a social wasteland.
Regardless of their status, all military, civil, judicial, and religious leaders would be removed in the day of judgment (39:7; 2 Kgs 24:14–16). God would eventually give his people good leaders again (Isa 1:26) but not diviners and others who used pagan forms of revelation (47:9, 12–13; see Deut 18:10–12).
Things would be so bad (a heap of ruins) that no one would want to take leadership. The people would become so desperate that anyone providing food or clothes (3:7) could be the leader of the people. In fact, however, no one would have food or clothing (see 4:1).
This passage applies the prophet’s teaching on arrogance (see 2:11–12) to the people of Jerusalem. An alternate understanding is that this passage applies specifically to the women of Jerusalem.
In a reversal of fortune, the affluent and proud people of Jerusalem would suffer disgrace. Some of their ornaments (3:18) likely were amulets to keep evil away, but they could not ward off the calamity of judgment. These items of beauty were status symbols and represented financial security.
