And which of you with taking thought can add to his stature one cubit?

People's New Testament

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.

Wesley's Notes

12:25 Which of you can add the least measure - It seems, to add one cubit to a thing (which is the phrase in the original) was a kind of proverbial expression for making the least addition to it.

Jamieson-Fausset-Brown Bible Commentary

25, 26. which of you, &c.-Corroding solicitude will not bring you the least of the things ye fret about, though it may double the evil of wanting them. And if not the least, why vex yourselves about things of more consequence?

Matthew Henry's Concise Commentary

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.
