Matthew 18:16-18

MLV(i) 16 But if he does not hear you, take with you one or two more, in order that, ‘at the mouth of two or three witnesses every declaration should be established.’ 17 But if he refuses to hear them, tell it to the congregation, and if he also refuses to hear the congregation, let him be just-like the Gentile and the tax collector to you.
18 Assuredly, I am saying to you again, As many things as you may bind upon the earth will have already been bound in heaven, and as many things as you may loose upon earth will have already been loosed in heaven.
