Acts 15:35-40

35Paul and Barnabas also remained in Antioch, teaching and preaching the word of the Lord, with many others also.

36Then after some days Paul said to Barnabas, “Let us now go back and visit our brethren in every city where we have preached the word of the Lord, and see how they are doing.”

37Now Barnabas was determined to take with them John called Mark.

38But Paul insisted that they should not take with them the one who had departed from them in Pamphylia, and had not gone with them to the work.

39Then the contention became so sharp that they parted from one another. And so Barnabas took Mark and sailed to Cyprus;

40but Paul chose Silas and departed, being commended by the brethren to the grace of God.
