Knowing the Affliction of His Own Heart

"If there is famine in the land, if there is pestilence or blight or mildew or locust or caterpillar, if their enemy besieges them in the land at their gates, whatever plague, whatever sickness there is, whatever prayer, whatever plea is made by any man or by all your people Israel, each knowing the affliction of his own heart and stretching out his hands toward this house, then hear in heaven your dwelling place and forgive and act and render to each whose heart you know, according to all his ways (for you, you only, know the hearts of all the children of mankind), that they may fear you all the days that they live in the land that you gave to our fathers.

1 Kings 8:37-40 ESV
