The fifth section of the Book of Exodus begins with the account of how Moses’ father-in-law, Jethro (Yitro in Hebrew) joins the Jewish people at Mount Sinai. It continues with the culmination of all human history since the creation: the Giving of the Torah. Sandwiched in between these two accounts is the narrative of how Jethro advised Moses – after Moses’ descent from Mount Sinai – to set up a judicial system.
