2 Chronicles 6:28 (KJV)

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;

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.

If there be dearth in the land, if there be pestilence, if there be blasting, or mildew, locusts, or caterpillers; if their enemies besiege them in the cities of their land; whatsoever sore or whatsoever sickness there be:

Then what prayer or what supplication soever shall be made of any man, or of all thy people Israel, when every one shall know his own sore and his own grief, and shall spread forth his hands in this house:

Then hear thou from heaven thy dwelling place, and forgive, and render unto every man according unto all his ways, whose heart thou knowest; (for thou only knowest the hearts of the children of men:)
