Dealing with Accusations
1Tim 5:19 Do not receive an accusation against an elder except from two or three witnesses.
In fact this principle was to be applied to everyone and not just elders. For Jesus said, "if your brother sins against you, go and tell him his fault between you and him alone. If he hears you, you have gained your brother. But if he will not hear, take with you one or two more, that `by the mouth of two or three witnesses every word may be established.' And if he refuses to hear them, tell it to the church." Mat 18:15-17
And Paul himself warned the Corinthians "This will be the third time I am coming to you. By the mouth of two or three witnesses every word shall be established." 2Cor 13:1
This principle comes from the Law which says, "One witness shall not rise against a man concerning any iniquity or any sin that he commits; by the mouth of two or three witnesses the matter shall be established." Deut 19:15
Notice that throughout 1Timothy he has either alluded to the Law or quoted it directly, as in the case of 5:18,19. Thus the Law of Moses has relevance to the Christian life.
