'Needed' in the Bible

Yes, I make my request to you, so that when I am with you I may not have to make use of the authority which may be needed against some to whom we seem to be walking after the flesh.

And when I was present with you, and was in need, I let no man be responsible for me; for the brothers, when they came from Macedonia, gave me whatever was needed; and in everything I kept myself from being a trouble to you, and I will go on doing so.
