'Needing' in the Bible

neither by the hands of men is He served -- needing anything, He giving to all life, and breath, and all things;

For though you should in fact be teachers by this time, you need someone to teach you the beginning elements of God's utterances. You have gone back to needing milk, not solid food.

But let this power have its full effect, so that you may be made complete, needing nothing.
