Luke 17:7 WEB

⁵  The apostles said to the Lord, 'Increase our faith.'

⁶  The Lord said, 'If you had faith like a grain of mustard seed, you would tell this sycamore tree, 'Be uprooted, and be planted in the sea,' and it would obey you.

⁷  But who is there among you, having a servant plowing or keeping sheep, that will say, when he comes in from the field, 'Come immediately and sit down at the table,'

⁸  and will not rather tell him, 'Prepare my supper, clothe yourself properly, and serve me, while I eat and drink. Afterward you shall eat and drink'?

⁹  Does he thank that servant because he did the things that were commanded? I think not.
