'Worthless' in the Bible

Thus says the Lord,“What injustice or unrighteousness did your fathers find in Me,That they have wandered far from MeAnd [habitually] walked after emptiness and futility and became empty?

Then the Lord said to me, “The [counterfeit] prophets are prophesying lies in My Name. I have neither sent them nor authorized them nor spoken to them. They are prophesying to you made-up visions [pretending to call forth responses from handmade gods], a worthless divination and the deceit of their own mind.

[Then said Jeremiah] “O Lord, my Strength and my Stronghold,And my Refuge in the day of distress and need,The nations will come to YouFrom the ends of the earth and say,‘Our fathers have inherited nothing but lies and illusion,[Worthless] things in which there is no benefit!’

They are worthless (empty, false, futile), a work of delusion and worthy of derision;In the time of their inspection and punishment they will perish.
