Connecting Statement:

Paul establishes that Christ is speaking through him and that Paul is wanting to restore them, encourage them, and unify them.

Every matter must be established by the mouth of two or three witnesses

Here a "matter" is an accusation and "mouth" is a metonym for the testimony a person gives through his mouth. This can be stated in active form. Alternate translation: "Believe that someone has done something wrong only after two or three people have given the same testimony" (See: rc://en/ta/man/jit/figs-activepassive and rc://en/ta/man/jit/figs-metonymy)
