Devastating Drought Was Brought on because of idol worship! This was against Judah, not Israel. See Good Kings and Bad Kings in Companion Vol. II.

Jeremiah 14.1. The word of the LORD* that came to Jeremiah concerning the droughts. 2. Judah mourns and its gates languish. They are black to the ground and the cry of Jerusalem has gone up. 3. And their nobles have sent their little ones for water. They came to the pits. Finding no water, they returned with their vessels empty. They were ashamed and confounded and covered their heads. 4. Because the ground is cracked, for there was no rain in the earth, the plowmen were ashamed, they covered their heads. 5. Yea, the deer also calved in the field and forsook the fawn, because there was no grass. 6. And the wild donkeys stood in the high places; they sniffed up the wind like jackals. Their eyes failed because there was no grass. 7. LORD*, though our iniquities testify against us, do it for Your name’s sake, for our backslidings are many. We have sinned against You 8. O, Hope of Israel, its Savior in time of trouble, why should You be like a stranger in the land and as a wayfaring man who turns aside to tarry a night? 9. Why should You be like a man overcome, like a mighty man who cannot save? Yet You, LORD*, are in our midst and we are called by Your name. Do not leave us!
