Acts 15:36-16:5 New Revised Standard Version (NRSV)
Paul and Barnabas Separate
36 After some days Paul said to Barnabas, “Come, let us return and visit the believers[a] in every city where we proclaimed the word of the Lord and see how they are doing.” 37 Barnabas wanted to take with them John called Mark. 38 But Paul decided not to take with them one who had deserted them in Pamphylia and had not accompanied them in the work. 39 The disagreement became so sharp that they parted company; Barnabas took Mark with him and sailed away to Cyprus. 40 But Paul chose Silas and set out, the believers[b] commending him to the grace of the Lord. 41 He went through Syria and Cilicia, strengthening the churches.
Timothy Joins Paul and Silas
16 Paul[c] went on also to Derbe and to Lystra, where there was a disciple named Timothy, the son of a Jewish woman who was a believer; but his father was a Greek. 2 He was well spoken of by the believers[d] in Lystra and Iconium. 3 Paul wanted Timothy to accompany him; and he took him and had him circumcised because of the Jews who were in those places, for they all knew that his father was a Greek. 4 As they went from town to town, they delivered to them for observance the decisions that had been reached by the apostles and elders who were in Jerusalem. 5 So the churches were strengthened in the faith and increased in numbers daily.
