'In the World' in the Bible

Look, you all have seen, and {why in the world} {have you become altogether vain}?

"But from where will wisdom be found? And {where in the world} [is the] place of understanding?

Indeed, from where does wisdom come? And {where in the world} [is the] place of understanding?

rejoicing in the world of his earth, and my delight [was] with the children of humankind.

And I will bring you down with [those who are] going down to the grave, {an ancient people}, and I will cause you to dwell in the world of [the] depths, in the ruins from of old with [those who are] going down to [the] grave, so that you will not be inhabited and {have a place} in [the] land of [the] living.
