'Anxious' in the Bible

Therefore I say unto you, be not anxious for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than the food, and the body than the raiment?

And which of you by being anxious can add one cubit unto the measure of his life?

And why are ye anxious concerning raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin:

Be not therefore anxious, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed?

Be not therefore anxious for the morrow: for the morrow will be anxious for itself. Sufficient unto the day is the evil thereof.

But when they deliver you up, be not anxious how or what ye shall speak: for it shall be given you in that hour what ye shall speak.
