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. 39I 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. 40This was my situation: The heat consumed me in the daytime and the cold at night, and sleep fled from my eyes. 41It 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.
