'Expended' in the Bible

Yet when I reflected on everything I had accomplished and on all the effort that I had expended to accomplish it, I concluded: "All these achievements and possessions are ultimately profitless -- like chasing the wind! There is nothing gained from them on earth."

But I thought, "I have worked in vain; I have expended my energy for absolutely nothing." But the Lord will vindicate me; my God will reward me.
