'Anxious' in the Bible

And Jesus answering said to her, 'Martha, Martha, thou art anxious and disquieted about many things,

'And when they bring you before the synagogues, and the rulers, and the authorities, be not anxious how or what ye may reply, or what ye may say,

And he said unto his disciples, 'Because of this, to you I say, Be not anxious for your life, what ye may eat; nor for the body, what ye may put on;

and who of you, being anxious, is able to add to his age one cubit?

If, then, ye are not able for the least -- why for the rest are ye anxious?
