'Hearts' in the Bible

But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.

And I will make an everlasting covenant with them, that I will not turn away from them, to do them good; but I will put my fear in their hearts, that they shall not depart from me.

For ye dissembled in your hearts, when ye sent me unto the LORD your God, saying, Pray for us unto the LORD our God; and according unto all that the LORD our God shall say, so declare unto us, and we will do it.

Kerioth is taken, and the strong holds are surprised, and the mighty men's hearts in Moab at that day shall be as the heart of a woman in her pangs.
