Tradition tells us that when the Twelve Tribes were encamped in the Wilderness, and ranged north, south, east and west, around the Tabernacle of the Congregation, they were placed under four ensigns or standards — Judah, Issachar, and Zebulon, by a Lion; Reuben, Simeon and Gad, by a Man; Ephraim, Manasseh and Benjamin, by an Ox; and Dan, Asher and Naphtali, by an Eagle.
Further details are to be found in “Smith’s Bible Dictionary”, in an article by Canon Bevan. Except allusions in Gen. xlix. 9, and Hosea x. 11, which lend support to the statement that two of the ensigns were a lion and ox, for Judah and Ephraim, the Bible is silent on the matter. Details, however, of the divisions in the Camp of Israel are found in Numbers ii. 3, 9,10, 16, 18, 24, 25 and 31
