'Emptiness' in the Bible

And the pelican and the bittern shall possess it, and the great owl and the raven shall dwell in it. And he shall stretch out upon it the line of waste, and the plummets of emptiness.

Behold, they are all vanity, their works are nought, their molten images are wind and emptiness.

Thou shalt eat, and not be satisfied, and thine emptiness shall remain in the midst of thee; and thou shalt take away, and not save; and what thou savest will I give up to the sword.
