In the Sinai Desert the Lord said to Moses,
The Israelites left Rephidim and arrived at the desert. Then two months after leaving Egypt, they arrived at the desert near Mount Sinai, where they set up camp at the foot of the mountain. This was two months after they had left Egypt.
But those from the Levi tribe were not included
Levi was the father of Gershon, Kohath, and Merari.
