The term 'A Tribe of Israel' refers to the twelve tribes of ancient Israel, which were divided into two distinct groups: the northern tribes of Ephraim (7 letters), Asher (5 letters), Levi (4 letters), DAN (3 letters), and Judah (5 letters); and the southern tribes of Levites (7 letters) and GAD (3 letters). These tribes were united under the leadership of Moses and Joshua, and were the descendants of the twelve sons of Jacob.
