'Anxious' in the Bible

When they bring you before the synagogues and the rulers and the authorities, do not worry about how or what you are to speak in your defense, or what you are to say;

And He said to His disciples, “For this reason I say to you, do not worry about your life, as to what you will eat; nor for your body, as to what you will put on.

And which of you by worrying can add a single hour to his life’s span?

If then you cannot do even a very little thing, why do you worry about other matters?
