'Anxious' in the Bible

"For this [reason] I say to you, do not be anxious for your life, what you will eat, and not for your body, what you will wear. Is your life not more than food and your body [more than] clothing?

And who among you, [by] being anxious, is able to add one hour to his life span?

And why are you anxious about clothing? Observe the lilies of the field, how they grow: they do not toil or spin,

Therefore do not be anxious, saying, 'What will we eat?' or 'What will we drink?' or 'What will we wear?,'

Therefore do not be anxious for tomorrow, because tomorrow will be anxious for itself. {Each day has enough trouble of its own.}

But whenever they hand you over, do not be anxious how [to speak] or what you should say, for what you should say will be given to you at that hour.
