When you read Exodus 18:13 it seems to be that Moses is superman. After his meeting with his father in low – in which he told him all the actions of God- the morning came and Moses left his leadership in order to judge his people, as written:
“וַיְהִי מִמָּחֳרָת וַיֵּשֶׁב מֹשֶׁה לִשְׁפֹּט אֶת-הָעָם; וַיַּעֲמֹד הָעָם עַל-מֹשֶׁה מִן-הַבֹּקֶר עַד-הָעָרֶב”
“And it came to pass on the morrow that Moses sat to judge the people: and the people stood by Moses from the morning unto the evening” (Exodus 18:13)
When a stranger or a guest come to a new place there are two ways to understand his visit: first, we are saying in Hebrew:”zar lo yavin”(a stranger won’t understand); second, we are saying in Hebrew :”Oreach le-rega’ ro’eh kol pega’”(a guest for a moment can see all the problems).
