1 Corinthians 11:13

No man is truly and thoroughly convinced of an error, till he be convicted by his own conscience. It is therefore very usual in holy writ for God, by his sacred penmen, to make appeals unto men's own consciences, and put them to judge within themselves, to examine a thing by their own reason, and according to the dictates of that to give sentence for or against themselves. The thing as to which he would have them judge within themselves, and accordingly pronounce sentence, was, whether it were a decent thing for women to pray to God with their hair all hanging loose about their shoulders, or without any veil, or covering for their head and face.
