Luke 12:29

And seek not what ye shall eat, or what ye shall drink,
&c.] 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).
