'Hearts' in the Bible

And as soon as we had heard it, our hearts did melt, neither did there remain any more spirit in any man, because of you: for Jehovah your God, he is God in heaven above, and on earth beneath.

And the men of Ai smote of them about thirty and six men; and they chased them from before the gate even unto Shebarim, and smote them at the descent; and the hearts of the people melted, and became as water.

For it was of Jehovah to harden their hearts, to come against Israel in battle, that he might utterly destroy them, that they might have no favor, but that he might destroy them, as Jehovah commanded Moses.

And, behold, this day I am going the way of all the earth: and ye know in all your hearts and in all your souls, that not one thing hath failed of all the good things which Jehovah your God spake concerning you; all are come to pass unto you, not one thing hath failed thereof.
