'Nothing' in the Bible

These things remind them of, testifying fully before the Lord -- not to strive about words to nothing profitable, but to the subversion of those hearing;

Do your best to present yourself to God as an approved worker who has nothing to be ashamed of, handling the word of truth with precision.

But have nothing to do with foolish and ignorant speculations [useless disputes over unedifying, stupid controversies], since you know that they produce strife and give birth to quarrels.
