Luke 17:8-10

Young's Literal Translation

⁸ but will not [rather] say to him, Prepare what I may sup, and having girded thyself about, minister to me, till I eat and drink, and after these things thou shalt eat and drink?

⁹ Hath he favour to that servant because he did the things directed? I think not.

¹⁰ `So also ye, when ye may have done all the things directed you, say -- We are unprofitable servants, because that which we owed to do -- we have done.'
