Neither be ye of doubtful mind - Or, in anxious suspense, μη μετεωριζεσθε. Raphelius gives several examples to prove that the meaning of the word is, to have the mind agitated with useless thoughts, and vain imaginations concerning food, raiment, and riches, accompanied with perpetual uncertainty.

And seek not what ye shall eat, or what ye shall drink,.... That is, in an anxious and distressing manner, with a tormenting and vexatious care; otherwise food is to be both asked of God every day, and to be sought for and after in the use of proper means:

neither be ye of doubtful minds; questioning and distrusting that ye shall have any thing to eat or drink: be not fickle, unstable, and inconstant, and wandering in your thoughts about these things, like the meteors in the air, which are carried about here and there; let not your minds be disturbed and distracted about them; or be anxiously solicitous for them; See Gill on Matthew 6:31.

Be ye of doubtful mind (μετεωρίζεσθε)

Only here in New Testament. The verb primarily means to raise to a height; buoy up, as with false hopes; and so to unsettle, or excite, or keep in fluctuation. Thus Thucydides says of the war between Athens and Sparta: "All Hellas was excited (μετέωρος) by the coming conflict between the two chief cities" (ii., 8).

And seek not ye what ye shall eat, or what ye shall drink, neither {i} be ye of doubtful mind.

(i) A metaphor taken of things that hang in the air, for those that care too much for this worldly life, and rely upon the arm of man, always have wavering and doubtful minds, swaying sometimes this way, and sometimes that way.

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.

12:29 Neither be ye of a doubtful mind - The word in the original signifies, any speculations or musings in which the mind fluctuates, or is suspended (like meteors in the air) in an uneasy hesitation.

neither...: or, live not in careful suspense

29. of doubtful, &c.-unsettled mind; put off your balance.

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.
