'Anxious' in the Bible

Therefore, I tell you, don't be anxious for your life: what you will eat, or what you will drink; nor yet for your body, what you will wear. Isn't life more than food, and the body more than clothing?

"Which of you, by being anxious, can add one moment to his lifespan?

Why are you anxious about clothing? Consider the lilies of the field, how they grow. They don't toil, neither do they spin,

"Therefore don't be anxious, saying, 'What will we eat?', 'What will we drink?' or, 'With what will we be clothed?'

Therefore don't be anxious for tomorrow, for tomorrow will be anxious for itself. Each day's own evil is sufficient.

But when they deliver you up, don't be anxious how or what you will say, for it will be given you in that hour what you will say.
