Acts 15:37-40

37 And Barnabas had a desire to take with them John, named Mark.

38 But Paul was of the opinion that it was not right to take with them one who had gone away from them in Pamphylia, and had not gone on with the work.

39 And there was a sharp argument between them, so that they were parted from one another, and Barnabas took Mark with him and went by ship to Cyprus;

40 But Paul took Silas and went away with the blessing of the brothers.
