7Who among you would say to your slave  who has just come in from plowing or tending sheep in the field, 'Come  here at once and take your place at the table'? 8Would you  not rather say to him, 'Prepare supper for me, put on your apron and  serve me while I eat and drink; later you may eat and drink'? 9Do you thank the slave for doing what was commanded? 10So  you also, when you have done all that you were ordered to do, say, 'We  are worthless slaves; we have done only what we ought to have done!'"
