'Anxious' in the Bible

But the Lord answered and said unto her, Martha, Martha, thou art anxious and troubled about many things:

And when they bring you before the synagogues, and the rulers, and the authorities, be not anxious how or what ye shall answer, or what ye shall say:

And he said unto his disciples, Therefore I say unto you, Be not anxious for your life, what ye shall eat; nor yet for your body, what ye shall put on.

And which of you by being anxious can add a cubit unto the measure of his life?

If then ye are not able to do even that which is least, why are ye anxious concerning the rest?
