'Worry' in the Bible

But when they bring you before the synagogues, the rulers, and the authorities, do not worry about how you should make your defense or what you should say,

Then Jesus said to his disciples, "Therefore I tell you, do not worry about your life, what you will eat, or about your body, what you will wear.

So if you cannot do such a very little thing as this, why do you worry about the rest?

So do not be overly concerned about what you will eat and what you will drink, and do not worry about such things.
