'Need' in the Bible

And [as for] you, the anointing which you received from him remains in you, and you do not have need that anyone teach you. But as his anointing teaches you about all [things], and is true and is not a lie, and just as it has taught you, you reside in him.

But whoever has the world's material possessions and observes his brother {in need} and shuts his heart against him, how does the love of God reside in him?
