'Change Of Heart' in the Bible

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.
