'Empty' in the Bible

Behold, the Lord lays waste to the earth, devastates it, twists and distorts its face and scatters its inhabitants.

Those who cause a person to be condemned with a [false] word,And lay a trap for him who upholds justice at the [city] gate,And defraud the one in the right with meaningless arguments.

“In fact, all of these [pagan prophets and priests] are false;Their works are worthless,Their cast images are [merely] wind and emptiness.

Then I said, “I have labored in vain,I have spent My strength for nothing and vanity (pride, uselessness);However My justice is with the Lord,And My reward is with My God.”
