'Futility' in the Bible

thus I have been made to inherit months of futility, and nights of sorrow have been appointed to me.

Just as there is futility in many dreams, so also in many words. Therefore, fear God!

For the creation was subjected to futility -- not willingly but because of God who subjected it -- in hope

So I say this, and insist in the Lord, that you no longer live as the Gentiles do, in the futility of their thinking.
