Cyril of Alexandria
Catena Aurea · Lukasevangelium 12
Consider the ravens: for they neither sow nor reap; which neither have storehouse nor barn; and God feedeth them: how much more are ye better than the fowls? And which of you with taking thought can add to his stature one cubit? If ye then be not able to do that thing which is least, why take ye thought for the rest?
Now whereas our Lord might have taken an example from the men who have cared least about earthly things, such as Elias, Moses, and John, and the like, He made mention of the birds, following the Old Testament, which sends us to the bee and the ant, and others of the same kind, in whom the Creator has implanted certain natural dispositions.
