Final answer:
In Biblical times, only members of the tribe of Judah could become king of Israel.
Step-by-step explanation:
In Biblical times, only members of the tribe of Judah could become king of Israel. This is because after the United Monarchy of Israel split into two separate kingdoms, the southern kingdom of Judah was ruled exclusively by descendants of King David from the tribe of Judah. The northern kingdom of Israel, on the other hand, had a succession of kings from various tribes. So, to become president in Biblical times, one had to be a member of the tribe of Judah.
