'Over anxious' in the Bible

For this reason I charge you not to be over-anxious about your lives, inquiring what you are to eat or what you are to drink, nor yet about your bodies, inquiring what clothes you are to put on. Is not the life more precious than its food, and the body than its clothing?

Which of you by being over-anxious can add a single foot to his height?

Do not be over-anxious, therefore, asking 'What shall we eat?' or 'What shall we drink?' or 'What shall we wear?'

Do not be over-anxious, therefore, about to-morrow, for to-morrow will bring its own cares. Enough for each day are its own troubles.
