Luke 12:24

By the ravens also he signifies something else, for the birds which pick up seeds have a ready source of food, but those that feed on flesh as the ravens do have more difficulty in getting it. Yet birds of this kind suffer from no lack of food, because the providence of God extends every where; but he brings to the same purpose also a third argument, saying, And which of you by taking thought can add to his stature?

But it is a great thing to follow up this example in faith. For to the birds of the air who have no labour of tilling, no produce from the fruitfulness of crops, Divine Providence grants an unfailing sustenance. It is true then that the cause of our poverty seems to be covetousness. For they have for this reason a toilless and abundant use of food, because they think not of claiming to themselves by any special right fruits given for common food. We have lost what things were common by claiming them as our own. For neither is any thing a man's own, where nothing is perpetual, nor is supply certain when the end is uncertain.

As before in raising our minds to spiritual boldness, He assured us by the example of the birds, which are counted of little worth, saying, Ye are of more value than many sparrows; so now also from the instance of birds, He conveys to us a firm and undoubting trust, saying, 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 fowls? 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.

That is, ye are more precious, because a rational animal like man is of a higher order in the nature of things than irrational things, as the birds are.

Now the reason that he omits mention of the other birds, and speaks only of the ravens, is, that the young of the ravens are by an especial providence fed by God. For the ravens produce indeed, but do not feed, but neglect their young, to whom in a marvellous manner from the air their food comes, brought as it were by the wind, which they receive having their mouths open, and so are nourished. Perhaps also such things were spoken by synecdoche, i. e. the whole signified by a part. Hence in Matthew our Lord refers to the birds of the air, (Matt. 6:26.) but here more particularly to the ravens, as being more greedy and ravenous than others.
