35But Paul and Barnabas stayed in Antioch, teaching and proclaiming the word of the Lord, with many others also.
36After some days Paul said to Barnabas, “Let’s return now and visit our brothers in every city in which we proclaimed the word of the Lord, to see how they are doing.”
37Barnabas planned to take Yochanan, who was called Mark, with them also.
