2 Chronicles 6:26-27

26When the heaven is shut up, and there is no rain, because they have sinned against thee; if they pray toward this place, and confess thy name, and turn from their sin, when thou dost afflict them:

27then hear thou in heaven, and forgive the sin of thy servants, and of thy people Israel, when thou teachest them the good way wherein they should walk; and send rain upon thy land, which thou hast given to thy people for an inheritance.
