'Worry' in the Bible

"Therefore I tell you, do not worry about your life, what you will eat or drink, or about your body, what you will wear. Isn't there more to life than food and more to the body than clothing?

Why do you worry about clothing? Think about how the flowers of the field grow; they do not work or spin.

So then, don't worry saying, 'What will we eat?' or 'What will we drink?' or 'What will we wear?'

So then, do not worry about tomorrow, for tomorrow will worry about itself. Today has enough trouble of its own.

Whenever they hand you over for trial, do not worry about how to speak or what to say, for what you should say will be given to you at that time.
