The heart is deceitful above all things, and desperately wicked: who can understand it? I the LORD search the heart, I try the mind, even to give every man according to his ways, and according to the fruit of his deeds.
Jeremiah 17:9-10
"And the LORD smelled a sweet savour; and the LORD said in his heart, I will not again curse the ground any more for man's sake; for the imagination of man's heart is evil from his youth; neither will I again smite any more every thing living, as I have done" (Gen. 8:21).
