Genesis 31:38-41

38These twenty years I have been with you. Your ewes and your female goats have not miscarried, and I have not eaten the rams of your flocks. 39What was torn by wild beasts I did not bring to you. I bore the loss of it myself. From my hand you required it, whether stolen by day or stolen by night. 40There I was: by day the heat consumed me, and the cold by night, and my sleep fled from my eyes. 41These twenty years I have been in your house. I served you fourteen years for your two daughters, and six years for your flock, and you have changed my wages ten times.
