Context
34Notwithstanding it pleased Silas to abide there still.
35Paul also and Barnabas continued in Antioch, teaching and preaching the word of the Lord, with many others also.
36And some days after Paul said unto Barnabas, Let us go again and visit our brethren in every city where we have preached the word of the Lord, how they do.
37And Barnabas determined to take with them John, whose surname was Mark.
38But Paul thought not good to take him with them, who departed from them from Pamphylia, and went not with them to the work.
39And the contention was so sharp between them, that they departed asunder one from the other: and so Barnabas took Mark, and sailed unto Cyprus;
40And Paul chose Silas, and departed, being recommended by the brethren unto the grace of God.
