Luke 17:10; 12:47-48

So you also, when you have done all that you were commanded, say, ‘We are unworthy servants; we have only done what was our duty.’

And that servant who knew his master’s will but did not get ready or act according to his will, will receive a severe beating. But the one who did not know, and did what deserved a beating, will receive a light beating. Everyone to whom much was given, of him much will be required, and from him to whom they entrusted much, they will demand the more. (ESV)
