Fyodor Dostoevsky,
The Brothers Karamazov — Part IV, Book X, Chapter 2
(1880)
“ Krassotkin began, getting up from the sofa, "can you swear by all you hold sacred in the world and something else besides, that you will watch vigilantly over the kids in my absence? I am going out.""And what am I going to swear for?" laughed Agafya. "I shall look after them without that.""No, you must swear on your eternal salvation. Else I shan't go.""Well, don't then. What does it matter to me? It's cold out; stay at home.""Kids," Kolya turned to the children, "this woman will stay with you till I come back or till your mother comes, for she ought to have been back long ago. ”
