One day, Moses was taking care of the sheep and goats of his father-in-law Jethro, the priest of Midian, and Moses decided to lead them across the desert to Sinai, the holy mountain.
Moses went to his father-in-law Jethro and asked, “Please let me return to Egypt to see if any of my people are still alive.” “All right,” Jethro replied. “I hope all goes well.”
Hobab the Midianite, the father-in-law of Moses, was there. And Moses said to him, “We're leaving for the place the LORD has promised us. He has said that all will go well for us. So come along, and we will make sure that all goes well for you.”
If you are unclean and refuse to be made clean by washing with the water mixed with ashes, you will be guilty of making my sacred tent unclean, and you will no longer belong to the people of Israel.
