Some translations set poetry farther to the right than the rest of the text to show that it is poetry. The ULB does this with the poetry in 14:1-10, 17-22.
The false prophets promised there would not be any war or drought. They gave people a false sense of hope, when they needed to repent. Because of this, Yahweh sent a drought and said that the false prophets would die of drought and war. This showed that these were not true prophets of Yahweh.
