Jeremiah 17:9-13 - The Deceitful Heart
9 Among all things living, man hath the most deceitful and unsearchable heart. Who shall then know it? 10 "Even I the LORD search out the ground of the heart, and try the reins, and reward every man according to his ways, and according to the fruit of his counsels." 11 The deceitful maketh a nest, but bringeth forth no young: He cometh by riches, but not righteously. In the midst of his life must he leave them behind him, and at the last be found a very fool.
12 But thou, O LORD, whose throne is most glorious, excellent and of most antiquity, which dwellest in the place of our holy rest: 13 Thou art the comfort of Israel. All that forsake thee, shall be ashamed. And they that depart from thee shall be written in the earth. For they have lost the LORD that is the fountain of the water of life.
