Matthew 18:17-19

Revised Standard Version

¹⁷ If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector. ¹⁸ Truly, I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven. ¹⁹ Again I say to you, if two of you agree on earth about anything they ask, it will be done for them by my Father in heaven.
