What does Isaiah 3:7 mean?

In this chapter Isaiah is describing a scene in Jerusalem's future. The Lord has removed all men of consequence from Judah. Everyone the people may have been trusting for provision and protection instead of their God will be taken away (Isaiah 3:2–3).

Without good leadership, the community has descended into chaos and lawlessness. Jerusalem is reduced to heaps of rubble, and the people live in poverty. It's so bad that owning a cloak is a luxury (Isaiah 3:6). Seeing a man with a cloak, one man says to another that he should become the leader of the people and rule over what is left of Judah.

Now in Isaiah 3:7 the man with the cloak responds. Instead of being arrogant, as Jerusalem's former leaders were, the man sees clearly that he cannot do anything to make the community better. He cries out that he cannot fix what Jerusalem and Judah have become. He insists that he, too, doesn't have enough food or clothing in his own home. He flatly refuses being appointed their leader.

When even those barely qualified to lead refuse the role, a community is truly in despair.
