2 Chronicles 6:28-30

28If there shall be famine in the land, if there be pestilence, if there be blighting, or mildew, locusts, or caterpillers; if their enemies shall besiege them in the cities of their land; whatever calamity or whatever sickness there be :1 29Then whatever prayer or whatever supplication shall be made by any man, or by all the people of Israel, when every one shall know his own calamity and his own grief, and shall spread forth his hands in this house:23 30Then hear thou from heaven thy dwelling place, and forgive, and render to every man according to all his ways, whose heart thou knowest; (for thou only knowest the hearts of the children of men:)
