1 Timothy 5:19-21

Refuse to listen to suspicious accusations against the pastors who lead the flock unless you have two or three witnesses to confirm the accusations. But if indeed you find that they have sinned, bring correction to them before the congregation so that the rest of the people will respect you. Timothy, in the presence of God and our Lord Jesus Christ, and before the chosen messengers, I solemnly charge you to put into practice all these matters without bias, prejudice, or favoritism.
