Acts 15:36-41

36And after some days Paul said unto Barnabas, Let us return now and visit our brethren in every city wherein we proclaimed the word of the Lord, and see how they fare. 37And Barnabas was minded to take with them John, who was called Mark. 38But Paul thought not good to take with them him who withdrew from them from Pamphylia, and went not with them to the work. 39There arose therefore a sharp contention, so that they parted asunder one from the other, and Barnabas took Mark with him, and sailed away unto Cyprus: 40but Paul chose Silas, and went forth, being commended by the brethren to the grace of God. 41And he went through Syria and Cilicia, confirming the churches.
