There is a serious dispute about the reading of the Greek text. I have followed Routh, who, relying on three mss. the Collectio of John of Antioch and the Latin versions, reads εἰ δὲ βδελύσσοιντο instead of the εἰ δὲ βούλοιντο of the ordinary text, which as Bp. Beveridge had pointed out before has no meaning unless a μὴ be introduced.
