'Hearts' in the Bible

And as soon as we had heard these things, our hearts did melt, neither did there remain any more courage in any man, because of you: for the LORD your God, he is God in heaven above, and in earth beneath.

Now it came about when all the kings of the Amorites who were beyond the Jordan to the west, and all the kings of the Canaanites who were by the sea, heard how the Lord had dried up the waters of the Jordan before the sons of Israel until they had crossed, that their hearts melted, and there was no spirit in them any longer because of the sons of Israel.

And the men of Ai smote of them about thirty and six men: for they chased them from before the gate even unto Shebarim, and smote them in the going down: wherefore the hearts of the people melted, and became as water.

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

My brothers who went with me caused the people’s hearts to melt with fear, but I remained loyal to the Lord my God.

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 the LORD your God spake concerning you; all are come to pass unto you, and not one thing hath failed thereof.

So now, go in fear of the Lord, and be his servants with true hearts: put away the gods worshipped by your fathers across the River and in Egypt, and be servants of the Lord.

“Then get rid of the foreign gods that are among you and offer your hearts to the Lord, the God of Israel.”
