Genesis 31:38-41
38 “I have been with you for twenty years now. Your sheep and goats have not miscarried, nor have I eaten rams from your flocks.
39 I did not bring you animals torn by wild beasts; I bore the loss myself. And you demanded payment from me for whatever was stolen by day or night.
40 This was my situation: The heat consumed me in the daytime and the cold at night, and sleep fled from my eyes.
41 It was like this for the twenty years I was in your household. I worked for you fourteen years for your two daughters and six years for your flocks, and you changed my wages ten times.
