Acts 15:36-39

36 But after some days, Paul said to Barnabas, Turn we again, and visit we brethren by all cities [Paul said to Barnabas, We turning again, visit our brethren by all cities], in which we have preached the word of the Lord, how they have them.

37 And Barnabas would take with him John, that was named Mark.

38 But Paul prayed him, that he that departed from them from Pamphylia, and went not with them into the work, should not be received.

39 And dissension was made, so that they departed atwain. And Barnabas took Mark, and came by boat to Cyprus.
