Amos 4:7-8

7“Also I myself have withheld from you the rain—when three months remain to the harvest, I caused it to rain on one city, while on another city I sent no rain; one piece of ground would get rain, while the portion not rained on would wither.

8So two or three cities go staggering to one city to drink water, but would not be satisfied— yet you have not returned to Me,” declares Adonai.
