'Useless' in the Bible

The priests quit asking, “Where is the Lord?”The experts in the law no longer knew Me,and the rulers rebelled against Me.The prophets prophesied by Baaland followed useless idols.

Has a nation ever exchanged its gods?(But they were not gods!)Yet My people have exchanged their Gloryfor useless idols.

Do not chase after other gods until your shoes wear out and your throats become dry. But you say, 'It is useless for you to try and stop me because I love those foreign gods and want to pursue them!'

The fiery bellows of judgment burn fiercely. But there is too much dross to be removed. The process of refining them has proved useless. The wicked have not been purged.

But they'll say, "It's useless! We will follow our plans and each of us will pursue his own evil desires.'

Go up to Gilead and get medicinal ointment, you dear poor people of Egypt. But it will prove useless no matter how much medicine you use; there will be no healing for you.
