Acts 15:38-40

³⁸But Paul didn't think it was a good idea to take him with them, since he'd left them in Pamphylia and hadn't continued working with them.

³⁹They had such a strong disagreement that they separated. Barnabas took Mark with him and sailed to Cyprus.

⁴⁰Paul chose Silas, and as they left, the believers committed them to the grace of the Lord.
