John
Acts 12:25
12:25 John. John Mark was a nephew of Barnabas (although some say he was a cousin—Colossians 4:10) and evidently a close friend of Peter (the early church fathers said much of what Mark wrote in his gospel was obtained from Peter). He probably was a Levite, like his uncle (Acts 4:36) and thus well instructed in the Scriptures, as well as from a prosperous family.
