Matthew 18:17-19

New Revised Standard Version, Anglicised

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