Acts 15:35

32 And Judas and Silas, who themselves were prophets, gave teaching to the brothers and made them strong in the faith.

33 And when they had been there for some time, they were sent back in peace by the brothers to those who had sent them.

35 But Paul and Barnabas kept on in Antioch, teaching and preaching the word of God, with a number of others.

36 And after some days, Paul said to Barnabas, Let us go back and see the brothers in every town where we have given the word of God, and see how they are.

37 And Barnabas had a desire to take with them John, named Mark.

38 But Paul was of the opinion that it was not right to take with them one who had gone away from them in Pamphylia, and had not gone on with the work.
