'Expend' in the Bible

Or the Lord will see your gloating and be displeased,And turn His anger away from your enemy.

What benefit do people get from all the effort which they expend on earth?

I'll expend my jealousy on you so they'll deal with you in anger. They'll cut off your noses and your ears. Your survivors will die violently. They'll take your sons and daughters away from you, but your survivors will be incinerated.
