Then it seemed good to the apostles and the elders, with the whole church, to choose men from among them and send them to Antioch with Paul and Barnabas. They sent Judas called Barsab’bas, and Silas, leading men among the brethren, with the following letter: “The brethren, both the apostles and the elders, to the brethren who are of the Gentiles in Antioch and Syria and Cili’cia, greeting. Since we have heard that some persons from us have troubled you with words, unsettling your minds, although we gave them no instructions, it has seemed good to us, having come to one accord, to choose men and send them to you with our beloved Barnabas and Paul, men who have risked their lives for the sake of our Lord Jesus Christ. We have therefore sent Judas and Silas, who themselves will tell you the same things by word of mouth. For it has seemed good to the Holy Spirit and to us to lay upon you no greater burden than these necessary things: that you abstain from what has been sacrificed to idols and from blood and from what is strangled and from unchastity. If you keep yourselves from these, you will do well. Farewell.” So when they were sent off, they went down to Antioch; and having gathered the congregation together, they delivered the letter. And when they read it, they rejoiced at the exhortation. And Judas and Silas, who were themselves prophets, exhorted the brethren with many words and strengthened them. And after they had spent some time, they were sent off in peace by the brethren to those who had sent them. But Paul and Barnabas remained in Antioch, teaching and preaching the word of the Lord, with many others also.
