'Works' in the Bible

And the king of Egypt saith unto them, 'Why, Moses and Aaron, do ye free the people from its works? go to your burdens.'

and the exactors are making haste, saying, 'Complete your works, the matter of a day in its day, as when there is straw.'

and the Feast of Harvest, the first fruits of thy works which thou sowest in the field; and the Feast of the In-Gathering, in the outgoing of the year, in thy gathering thy works out of the field.
