'Vanity' in the Bible

Woe unto them that draw iniquity with cords of vanity, and sin as it were with a cart rope:

And his breath, as an overflowing stream, shall reach to the midst of the neck, to sift the nations with the sieve of vanity: and there shall be a bridle in the jaws of the people, causing them to err.

All nations before him are as nothing; and they are counted to him less than nothing, and vanity.

That bringeth the princes to nothing; he maketh the judges of the earth as vanity.

Behold, they are all vanity; their works are nothing: their molten images are wind and confusion.

They that make a graven image are all of them vanity; and their delectable things shall not profit; and they are their own witnesses; they see not, nor know; that they may be ashamed.

When thou criest, let thy companies deliver thee; but the wind shall carry them all away; vanity shall take them: but he that putteth his trust in me shall possess the land, and shall inherit my holy mountain;

Then shalt thou call, and the LORD shall answer; thou shalt cry, and he shall say, Here I am. If thou take away from the midst of thee the yoke, the putting forth of the finger, and speaking vanity;

None calleth for justice, nor any pleadeth for truth: they trust in vanity, and speak lies; they conceive mischief, and bring forth iniquity.
