'Repent' in the Bible

And saying, Repent ye: for the kingdom of heaven is at hand.

From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand.

Then He proceeded to denounce the towns where most of His miracles were done, because they did not repent:

and said, “I assure you and most solemnly say to you, unless you repent [that is, change your inner self—your old way of thinking, live changed lives] and become like children [trusting, humble, and forgiving], you will never enter the kingdom of heaven.

For John came unto you in the way of righteousness, and ye believed him not; but the publicans and the harlots believed him: and ye, when ye saw it, did not even repent yourselves afterward, that ye might believe him.
