In the third month, when the children of Israel were gone forth out of the land of Egypt, the same day came they into the wilderness of Sinai. The greater part of the time since the departure out of Egypt, on the fifteenth day of the first month, had apparently been spent at Elim and at Rephidim, and it was not until the third month that the great army came into the desert of Sinai proper.
