Luke 17:8
And will not rather say unto him, Make ready wherewith I may sup, and gird thyself, and serve me, till I have eaten and drunken; and afterward thou shalt eat and drink? And will not rather say unto him, Make ready wherewith I may sup, and gird thyself, and serve me, till I have eaten and drunken; and afterward thou shalt eat and drink?
The servant in the verse comes in from labor in the field and is still required to make ready his master's supper and wait upon him at table before taking food and drink himself. The order is fixed: first the master's meal is prepared and served through to the end of his eating and drinking, and only afterward does the servant eat and drink. Finishing the assigned work in the field does not release him from this further service in the house.
Doing exactly what was assigned earns the servant no claim to special thanks or credit, for such service is duty and not merit. It gives no ground for superiority over others, but calls for lowly, humble service. There is therefore no place for proud boasting about one's own work, nor for despising or treating as inferior the service rendered by fellow workers.
