'Need' in the Bible

For from you hath sounded forth the word of the Lord, not only in Macedonia and Achaia, but in every place your faith to God-ward is gone forth; so that we need not to speak anything.

But concerning love of the brethren ye have no need that one write unto you: for ye yourselves are taught of God to love one another;

that ye may walk becomingly toward them that are without, and may have need of nothing.

But concerning the times and the seasons, brethren, ye have no need that aught be written unto you.
