John Chrysostom — as excerpted in the Catena Aurea on Matthew 6:28-30

“(Hom. xxii.) Having shewn that it is not right to be anxious about food, He passes to that which is less; (for raiment is not so necessary as food;) and asks, And why are ye careful wherewith ye shall be clothed? He uses not here the instance of the birds, when He might have drawn some to the point, as the peacock, or the swan, but brings forward the lilies, saying, Consider the lilies of the field. He would prove in two things the abundant goodness of God; to wit, the richness of the beauty with which they are clothed, and the mean value of the things so clothed with it.”
