2 Chronicles 6:26-27

26 ¶ When the heaven is shut up, and there is no rain, because they have sinned against thee; yet if they pray toward this place, and confess thy name, and turn from their sin, when thou dost afflict them; 27 Then hear thou from heaven, and forgive the sin of thy servants, and of thy people Israel, when thou hast taught them the good way, wherein they should walk; and send rain upon thy land, which thou hast given unto thy people for an inheritance.
