29 That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves, ye shall do well. Fare ye well.

30 So when they were dismissed, they came to Antioch: and when they had gathered the multitude together, they delivered the epistle:

31 Which when they had read, they rejoiced for the consolation.

32 And Judas and Silas, being prophets also themselves, exhorted the brethren with many words, and confirmed them.

33 And after they had tarried there a space, they were let go in peace from the brethren unto the apostles.

34 Notwithstanding it pleased Silas to abide there still.

35 Paul also and Barnabas continued in Antioch, teaching and preaching the word of the Lord, with many others also.

36 And 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, and see how they do.

37 And Barnabas determined to take with them John, whose surname was Mark.

38 But Paul thought not good to take him with them, who departed from them from Pamphylia, and went not with them to the work.

39 And the contention was so sharp between them, that they departed asunder one from the other: and so Barnabas took Mark, and sailed unto Cyprus;

40 And Paul chose Silas, and departed, being recommended by the brethren unto the grace of God.

41 And he went through Syria and Cilicia, confirming the churches.

1 Corinthians 5:1
5 It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father’s wife.

Matthew 18:15-17
15 Moreover if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother.

16 But if he will not hear thee, then take with thee one or two more, that in the mouth of two or three witnesses every word may be established.

17 And if he shall neglect to hear them, tell it unto the church: but if he neglect to hear the church, let him be unto thee as an heathen man and a publican.

Ephesians 4:29
29 Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
