And why take you thought for clothing? Consider the lilies of the field, how they grow; they toil not, neither do they spin:
Read Chapter 6
Augustine of Hippo
AD 430
But these examples are not to be treated as allegories, so that we should inquire what the fowls of heaven or the lilies of the field mean: for they stand here, in order that from smaller matters we may be persuaded respecting greater ones; just as is the case in regard to the judge who neither feared God nor regarded man, and yet yielded to the widow who often importuned him to consider her case, not from piety or humanity, but that he might be saved annoyance. For that unjust judge does not in any way allegorically represent the person of God; but yet as to how far God, who is good and just, cares for those who supplicate Him, our Lord wished the inference to be drawn from this circumstance, that not even an unjust man can despise those who assail him with unceasing petitions, even were his motive merely to avoid annoyance.
Having spoken of our necessary food, and having signified that not even for this should we take thought, He passes on in what follows to that which is more easy. For raiment is not so necessary as food.
Why then did He not make use here also of the same example, that of the birds, neither mention to us the peacock, and the swan, and the sheep? For surely there were many such examples to take from thence. Because He would point out how very far the argument may be carried both ways: both from the vileness of the things that partake of such elegance, and from the munificence vouchsafed to the lilies, in respect of their adorning. For this cause, when He has decked them out, He does not so much as call them lilies any more, but grass of the field. Matthew 6:30 And He is not satisfied even with this name, but again adds another circumstance of vileness, saying, which today is. And He said not, and tomorrow is not, but what is much baser yet, is cast into the oven. And He said not, cloth...
He shames us not only by the birds, which lack reason, but also by the lilies, that wither. If God adorned the lilies in such a manner, without any necessity to do so, how much more will He fulfill our own need for clothing? He shows that though you go to great lengths, you are not able to be adorned as beautifully as the lilies. Even Solomon the most wise and splendid, with all his kingdom at his disposal, could not array himself in such a manner.
