2 Chronicles 6:28-30

28If there be in the land famine, if there be pestilence, if there be blasting or mildew, locust or caterpiller; if their enemies besiege them in the land of their cities; whatsoever plague or whatsoever sickness there be;

29what prayer and supplication soever be made by any man or by all thy people Israel, which shall know every man his own plague and his own sorrow, and shall spread forth his hands toward this house:

30then hear thou from heaven thy dwelling place, and forgive, and render unto every man according to all his ways, whose heart thou knowest; (for thou, even thou only, knowest the hearts of the children of men;)
