Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Matthew 28:19 (KJV)
He that believeth and is baptized shall be saved; but he that believeth not shall be damned. Mark 16:16 (KJV)
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)
