'Labours' in the Bible

Lest strangers be filled with thy power, And thy labours in the house of a stranger,

'Why have we fasted, and Thou hast not seen? We have afflicted our soul, and Thou knowest not.' Lo, in the day of your fast ye find pleasure, And all your labours ye exact.

And Ephraim saith: 'Surely I have become rich, I have found wealth for myself, All my labours -- they find not against me iniquity that is sin.'
