These twenty years I have been in your house; I served you fourteen years for your two daughters and six years for [my share of] your flocks, and you have changed my wages ten times.

Then Pharaoh sent and called for Joseph, and they hurriedly brought him out of the dungeon; and when Joseph shaved himself and changed his clothes [making himself presentable], he came to Pharaoh.
