'Hearts' in the Bible

He has made everything appropriate in its time. He has also put eternity in their hearts, but man cannot discover the work God has done from beginning to end.

It is better to go to the house of weeping, than to go to the house of feasting; because that is the end of every man, and the living will take it to their hearts.

The hearts of the wise are in the house of weeping; but the hearts of the foolish are in the house of joy.

Because the sentence against an evil deed is not executed quickly, therefore the hearts of the sons of men among them are given fully to do evil.

This is an evil in all that is done under the sun: there is one fate for everyone. In addition, the hearts of people are full of evil, and madness is in their hearts while they live—after that they go to the dead.
