'Repenting' in the Bible

Thou hast cast me off, saith Jehovah, thou art gone backward; and I have stretched out my hand against thee, and will destroy thee: I am become weary of repenting.

And he answering said, I will not; but afterwards repenting himself he went.

I say unto you, that thus there shall be joy in heaven for one repenting sinner, more than for ninety and nine righteous who have no need of repentance.

Thus, I say unto you, there is joy before the angels of God for one repenting sinner.
