To baptize is to wash or clean (perhaps by immersing or dipping into water) as a symbolic gesture signifying a repentance or commitment.
Key verse about Baptize: “I baptize you with water for repentance. But after me comes one who is more powerful than I, whose sandals I am not worthy to carry. He will baptize you with the Holy Spirit and fire (Matthew 3:11, NIV).
