'Need' in the Bible

From Him the whole body [the church, in all its various parts], joined and knitted firmly together by what every joint supplies, when each part is working properly, causes the body to grow and mature, building itself up in [unselfish] love.

The thief [who has become a believer] must no longer steal, but instead he must work hard [making an honest living], producing that which is good with his own hands, so that he will have something to share with those in need.

Do not let unwholesome [foul, profane, worthless, vulgar] words ever come out of your mouth, but only such speech as is good for building up others, according to the need and the occasion, so that it will be a blessing to those who hear [you speak].
