Mystically; The work of the mill is a toil of blindness, for the beasts having their eyes closed are driven round in a circle, and under the type of an ass we often find the Gentiles figured, who are held in the ignorance of blind labour; while the Jews have the path of knowledge set before them in the Law, who if they offend Christ’s Apostles it were better for them, that having their necks made fast to a mill-stone, they should be drowned in the sea, that is, kept under labour and in the depths of ignorance, as the Gentiles; for it were better for them that they should have never known Christ, than not to have received the Lord of the Prophets.
