'Emptiness' in the Bible

“Surely every man walks around like a shadow [in a charade];Surely they make an uproar for nothing;Each one builds up riches, not knowing who will receive them.

Men of low degree are only a breath (emptiness), and men of [high] rank are a lie (delusion).In the balances they go up [because they have no measurable weight or value];They are together lighter than a breath.

Therefore He consumed their days like a breath [in emptiness and futility]And their years in sudden terror.

Remember how fleeting my lifetime is;For what vanity, [for what emptiness, for what futility, for what wisp of smoke] You have created all the sons of men!
