But 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. Then the contention became so sharp that they parted from one another. And so Barnabas took Mark and sailed to Cyprus; but Paul chose Silas and departed, being commended by the brethren to the grace of God."
