Jeremiah 16:13

therefore will I cast you out of this land into a land that ye know not, neither ye nor your fathers, a country altogether strange to them, and there shall ye serve other gods day and night, without intermission; where I will not show you favor. This is a form of holy irony: what they willingly did in their own country, they would be obliged to do in the land of their captivity; because they voluntarily forsook the true God at home, they would be prevented from serving Him elsewhere. At the same time the Lord opens up before the eyes of Judah a way of redemption, the thought of which was intended to keep His people from despair.
