See this passage explained in the notes at Matthew 6:25-33.

Take no thought - Be not anxiously careful. See on Matthew 6:25 (note).

And he said unto his disciples,.... Having finished the parable which he spake to the whole audience in common, he directed himself to his disciples, who were poor, and apt to be over anxious about their living in the world:

therefore I say unto you, take no thought for your life, what ye shall eat. The Ethiopic version adds, "and what ye shall drink"; and so a manuscript in Gonvill and Caius College in Cambridge, which seems to be transcribed from Matthew 6:27 life is very near and dear to man; all that a man has, he will give for it; and it is his duty to be careful to preserve it, and to make use of means for the support of it; but then, as he should not be dainty about the food he eats, and should refuse no good creature of God, but receive it with thanksgiving, so he should not distress himself for fear of wanting bread, nor distrust the promises of God, and a supply from him; but should cast all his care upon the Lord, who daily cares for him:

neither for the body, what ye shall put on: it is highly proper and necessary that the body should be clothed, partly for decency, and partly to secure it from the inclemency of the weather; but then persons should not be difficult and over nice about what they wear, nor be distressed, fearing they should be clothed with rags; but should trust in the Lord, who gives food and raiment, and all things richly to enjoy.

Take no thought

See on Matthew 6:25.

{7} And he said unto his disciples, Therefore I say unto you, Take no thought for your life, what ye shall eat; neither for the body, what ye shall put on.

(7) Earnestly thinking upon the providence of God is a present remedy for this life against the most foolish and wasting worry of men.

12:22-31 Be not anxious for your life. These verses are found in almost the same words in Mt 6:24-34. See notes there.

12:22 Mt 6:25.

22-31. (See on [1649]Mt 6:25-33).

12:22-40 Christ largely insisted upon this caution not to give way to disquieting, perplexing cares, Mt 6:25-34. The arguments here used are for our encouragement to cast our care upon God, which is the right way to get ease. As in our stature, so in our state, it is our wisdom to take it as it is. An eager, anxious pursuit of the things of this world, even necessary things, ill becomes the disciples of Christ. Fears must not prevail; when we frighten ourselves with thoughts of evil to come, and put ourselves upon needless cares how to avoid it. If we value the beauty of holiness, we shall not crave the luxuries of life. Let us then examine whether we belong to this little flock. Christ is our Master, and we are his servants; not only working servants, but waiting servants. We must be as men that wait for their lord, that sit up while he stays out late, to be ready to receive him. In this Christ alluded to his own ascension to heaven, his coming to call his people to him by death, and his return to judge the world. We are uncertain as to the time of his coming to us, we should therefore be always ready. If men thus take care of their houses, let us be thus wise for our souls. Be ye therefore ready also; as ready as the good man of the house would be, if he knew at what hour the thief would come.
