'Heart' in the Bible

So keep in mind where you were at first, and be changed in heart and do the first works; or I will come to you, and will take away your light from its place, if your hearts are not changed.

See, then, that you have a change of heart; or I will come to you quickly, and will make war against them with the sword of my mouth.

And I gave her time for a change of heart, but she has no mind to give up her unclean ways.

Keep in mind, then, the teaching which was given to you, and be ruled by it and have a change of heart. If then you do not keep watch, I will come like a thief, and you will have no knowledge of the hour when I will come on you.

To all those who are dear to me, I give sharp words and punishment: then with all your heart have sorrow for your evil ways.

As she gave glory to herself, and became more evil in her ways, in the same measure give her pain and weeping: for she says in her heart, I am seated here a queen, and am no widow, and will in no way see sorrow.
