'Repented' in the Bible

For this shall the earth mourn, and the heavens above be black; because I have spoken it, I have purposed it, and I have not repented, neither will I turn back from it.

And let that man be as the cities which Jehovah overthrew, and repented not: and let him hear a cry in the morning, and shouting at noontime;

Did Hezekiah king of Judah and all Judah put him to death? did he not fear Jehovah, and entreat the favor of Jehovah, and Jehovah repented him of the evil which he had pronounced against them? Thus should we commit great evil against our own souls.

Surely after that I was turned, I repented; and after that I was instructed, I smote upon my thigh: I was ashamed, yea, even confounded, because I did bear the reproach of my youth.
