Luke 17:7-9

7But if you have a slave who is plowing or tending sheep, who among you will say to him when he comes in from the field, ‘Come right in, and recline at table’?

8But won’t he instead say to him, ‘Prepare something for me to eat! Dress yourself and wait on me while I eat and drink; and afterward, you may eat and drink’?

9He doesn’t thank the slave because he did what he was commanded, does he?
