'Repented' in the Bible

For this the earth will 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."

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