“Therefore I say unto you, take no thought.” Thus, after He hath shown the hurt to be unspeakable, then and not before He makes the commandment stricter; in that He not only bids us cast away what we have, but forbids to take thought even for our necessary food, saying, “Take no thought for your soul, what ye shall eat.” Not because the soul needs food, for it is incorporeal; but He spake according to the common custom. For though it needs not food, yet can it not endure to remain in the body, except that be fed. And in saying this, He puts it not simply so, but here also He brings up arguments, some from those things which we have already, and some from other examples.
