Deuteronomy 12:32

What thing soever I command you, observe to do it: thou shalt not add thereto, nor diminish from it.

Ver. 32. Thou shalt not add thereto.] To add anything to the Word of God, saith Theodoret, is bold madness; but to open those things by the Word, that in the Word are more darkly delivered, is both lawful and laudable.
