'Hearts of the Sons of Men' in the Bible

then hear from heaven Your dwelling place, and forgive, and render to each according to all his ways, whose heart You know for You alone know the hearts of the sons of men,

Sheol and destruction are before Jehovah, Surely also the hearts of the sons of men.

Because the sentence against an evil act is not executed quickly, the hearts of the sons of men are fully set to do evil.

This is evil in all things which are done under the sun: that there is one fate for all, and the hearts of the sons of men are full of evil; while they have life their hearts are foolish, and after that--to the dead.
