11 - Judah has fornicated with other gods, and so will fall. Men from Jeremiah's hometown conspire to kill him, but God promises they will die, instead of him.
12 - Why do you let the wicked prosper, Lord? "You can't even handle your own clan, why are you worrying about the nations?" God will uproot Judah and her enemies, but will replant Judah.
13 - Judah is like soiled underwear, refusing to be worn or washed. Israel will be drunk and dashed and destroyed. Exile is coming for the greatness of her iniquity. She cannot change and stop sinning, like the leopard can't change his spots.
