'Futility' in the Bible

Then the Lord said to me, “The prophets are prophesying falsehood in My name. I have neither sent them nor commanded them nor spoken to them; they are prophesying to you a false vision, divination, futility and the deception of their own minds.

O Lord, my strength and my stronghold,And my refuge in the day of distress,To You the nations will comeFrom the ends of the earth and say,“Our fathers have inherited nothing but falsehood,Futility and things of no profit.”

Thus says the Lord of hosts,“Do not listen to the words of the prophets who are prophesying to you.They are leading you into futility;They speak a vision of their own imagination,Not from the mouth of the Lord.
