Repent (1):To lament one's actions; turn again. And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. And it REPENTED the LORD that he had made man on the earth, and it grieved him at his heart. (Gen 1:6-6) (2):To change one's mind purpose regret. From that time Jesus began to preach, and to say, REPENT: for the kingdom of heaven is at hand. (Mat 4,17)
