Amos 4:7-8
7
"I also have withheld the rain from you, when there were yet three months to the harvest; and I caused it to rain on one city, and caused it not to rain on another city. one place was rained on, and the piece where it didn't rain withered.
8
So two or three cities staggered to one city to drink water, and were not satisfied: yet you haven't returned to me," says Yahweh.
