'Labored' in the Bible

"But stand up now with your spells and your many incantations, at which you have labored from your childhood until today,

“So have those become to you with whom you have labored,Who have trafficked with you from your youth;Each has wandered in his own way;There is none to save you.

But I myself said: I have labored in vain,I have spent my strength for nothing and futility;yet my vindication is with the Lord,and my reward is with my God.

The Lord has sworn with His right handand His strong arm:I will no longer give your grainto your enemies for food,and foreigners will not drink your new wineyou have labored for.
