2 Chronicles 7:13-14

If, at my word, heaven is shut up, so that there is no rain, or if I send locusts on the land for its destruction, or if I send disease on my people; If my people, on whom my name is named, make themselves low and come to me in prayer, searching for me and turning from their evil ways; then I will give ear from heaven, overlooking their sin, and will give life again to their land.
