Lukáš 17:10

Tak i vy, když učiníte všecko, což vám přikázáno, rcete: Služebníci neužiteční jsme. Což jsme povinni byli učiniti, učinili jsme.

So likewise ye, when ye shall have done all those things which are commanded you, say, We are unprofitable servants: we have done that which was our duty to do.
