Thus, four Tribes, with three Tribes in each direction (North, South, East and West) and the Levites in the center were to set up camp according to the following Biblical specifications during their Egyptian exodus and wilderness travels. It is recorded that Judah and two other Tribes camped on the eastern side of the congregation, Reuben and two other Tribes on the southern, Ephraim and two other Tribes on the western, Dan and two other Tribes on the northern, while the Levites camped alone in their center.
Meanwhile, Jewish tradition also suggests that the ‘standard/symbol’ for the Tribe of Judah was a Lion, the standard for the Tribe of Reuben was a Man's Face, the standard for the Tribe of Ephraim was an Ox and the standard for the Tribe of Dan was a Serpent, (Gen. 49:17) which was later changed to an Eagle.
