Jethro, who had come to Moses shortly before the revelation on Mount Sinai, stayed with his son-in-law for more than a year. In the first months, however, he had no opportunity of observing Moses in the capacity of judge, for Moses spent the time from the day of the revelation to the tenth day of Tishri almost entirely in heaven. Hence Jethro could not be present at a court proceeding of his before the eleventh day of Tishri, the first day after Moses' return from heaven.
Jethro now perceived how Moses sat like a king upon his throne, while the people, who brought their lawsuits before him, stood around him. This so displeased him that he said to his son-in-law: "Why sittest thou thyself alone, and all the people stand by thee from morning until even?" Moses answered: "Because the people come unto me to enquire of God. It is not in my honor that they stand, but in honor of God, whose judgement they would know.
When they are in doubt over a case of clean or unclean, or when there is a dispute between two parties, which they desire to have settled exactly according to the law, or in conformity with a compromise, they come to me; and when the parties at dispute leave me, they part as friends and no longer enemies. I expound to the people, besides, the words of God and His decisions."
