What is the definition of repent?

“To change one's mind for the better, heartily to amend with abhorrence of one's past sins” – Thayer’s Greek Lexicon

Repentance is turning from sin and turning to God.

"For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death." - 2 Corinthians 7:10 KJV

Another translation:

“For the kind of sorrow God wants us to experience leads us away from sin and results in salvation. There’s no regret for that kind of sorrow. But worldly sorrow, which lacks repentance, results in spiritual death.” - 2 Corinthians 7:10 NLT.

"Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost." - Acts 2:38 KJV
