Genesis 31:6, 38-40

And you know that with all my might I have served your father.

These twenty years I have been with you; your ewes and your female goats have not miscarried their young, and I have not eaten the rams of your flock. That which was torn by beasts I did not bring to you; I bore the loss of it. You required it from my hand, whether stolen by day or stolen by night. There I was! In the day the drought consumed me, and the frost by night, and my sleep departed from my eyes.
