From Matthews

 6.25) Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more than food, and the body more than clothes? 26) Can any one of you by worrying add a single hour to your life? 31) Do not worry then, saying, "What will we eat?" or "What will we drink?" or "What will we wear for clothing?" 32) For the Gentiles eagerly seek all these things; for your heavenly Father knows that you need all these things. 33) But seek first His kingdom and His righteousness, and all these things will be added to you. 34) So do not worry about tomorrow; for tomorrow will care for itself. Each day has enough trouble of its own.
