'Labored' in the Bible

Stand, now, in your enchantments, and in your many sorceries with which you have labored from your youth. Perhaps you may be able to benefit; perhaps you may {scare away}.

So are to you [those with] whom you have labored, your traders from your youth. They wander, each to his side; there is no one who can save you.

But I myself said, "I have labored in vain; I have used up my strength for nothing and vanity! Nevertheless, my justice [is] with Yahweh, and my reward [is] with my God."

Yahweh has sworn by his right hand, and by {his mighty arm}, "Surely I will never again give your grain [as] food to {your enemies}, and surely {foreigners} shall not drink your new wine at which you have labored."
