Was mark associated with Paul Barnabas timothy and peter?

Yes, Mark, also known as John Mark, was associated with Paul, Barnabas, Timothy, and Peter in the New Testament. He accompanied Paul and Barnabas on their first missionary journey but later left them, which caused a disagreement between Paul and Barnabas. Mark later reconciled with Paul and was mentioned as a useful companion for ministry. Additionally, he is traditionally considered the author of the Gospel of Mark, which is thought to reflect Peter's teachings.
