Catena Aurea on Luke 9:10–17: Augustine of Hippo

That Luke says here, that the men were ordered to sit down by fifties, but Mark, by fifties and hundreds, does not matter, seeing that one spoke of a part, the other of the whole. But if one had mentioned only the fifties, and the other only the hundreds, they would seem to be greatly opposed to one another; nor would it be sufficiently distinct which of the two was said. But who will not admit, that one was mentioned by one Evangelist, the other by another, and that if more attentively considered it must be found so. But I have said thus much, because often certain things of this kind exist, which to those who take little heed and judge hastily appear contrary to one another, and yet are not so.
