'Useless' in the Bible

“Should he argue with useless talk,Or with words which are not profitable?

You have rejected all those who wander from Your statutes,For their deceitfulness is useless.

Indeed, it is useless to spread the baited netIn the sight of any bird;

Yet our eyes failed,Looking for help was useless;In our watching we have watchedFor a nation that could not save.

It is useless either for the soil or for the manure pile; it is thrown out. He who has ears to hear, let him hear.”

All have turned aside, together they have become useless;There is none who does good,There is not even one.”

and again, “The Lord knows the reasonings of the wise, that they are useless.”

Remind them of these things, and solemnly charge them in the presence of God not to wrangle about words, which is useless and leads to the ruin of the hearers.

who formerly was useless to you, but now is useful both to you and to me.

But are you willing to recognize, you foolish fellow, that faith without works is useless?

For if these qualities are yours and are increasing, they render you neither useless nor unfruitful in the true knowledge of our Lord Jesus Christ.
