In all these three sentences there are some words understood. In the first indeed, as many copies read “without cause,” there is nothing to be supplied. In the second, “He who saith to his brother, Racha,” we must supply the words, “without cause;” and again, in “He who says, Thou fool,” two things are understood, “to his brother,” and, “without cause.” All this forms the defence of the Apostle, when he calls the Galatians fools, though he considers them his brethren; for he did it not without cause.
