'Laboured' in the Bible

Stand, I pray thee, in thy charms, And in the multitude of thy sorceries, In which thou hast laboured from thy youth, It may be thou art able to profit, It may be thou dost terrify!

So have they been to thee with whom thou hast laboured, Thy merchants from thy youth, Each to his passage they have wandered, Thy saviour is not!

And I said, 'For a vain thing I laboured, For emptiness and vanity my power I consumed, But my judgment is with Jehovah, And my wage with my God.

In the greatness of thy way thou hast laboured, Thou hast not said, 'It is desperate.' The life of thy hand thou hast found, Therefore thou hast not been sick.

Sworn hath Jehovah by His right hand, Even by the arm of His strength: 'I give not thy corn any more as food for thine enemies, Nor do sons of a stranger drink thy new wine, For which thou hast laboured.
