'Vanity' in the Bible

They have seen vanity and lying divination, saying, The LORD saith: and the LORD hath not sent them: and they have made others to hope that they would confirm the word.

Therefore thus saith the Lord GOD; Because ye have spoken vanity, and seen lies, therefore, behold, I am against you, saith the Lord GOD.

And mine hand shall be upon the prophets that see vanity, and that divine lies: they shall not be in the assembly of my people, neither shall they be written in the writing of the house of Israel, neither shall they enter into the land of Israel; and ye shall know that I am the Lord GOD.

Therefore ye shall see no more vanity, nor divine divinations: for I will deliver my people out of your hand: and ye shall know that I am the LORD.

Whiles they see vanity unto thee, whiles they divine a lie unto thee, to bring thee upon the necks of them that are slain, of the wicked, whose day is come, when their iniquity shall have an end.

And her prophets have daubed them with untempered morter, seeing vanity, and divining lies unto them, saying, Thus saith the Lord GOD, when the LORD hath not spoken.
