Final answer:
The claim that Saul had to be the tenth generation from Perez to be the rightful king is not substantiated by biblical or archaeological records.
Step-by-step explanation:
The statement that Saul was not the tenth generation of Judah's son Perez and thus could not be the rightful King of Israel is not directly supported by biblical or archaeological evidence.
The historical context of King Saul's reign over Israel indicates his appointment as king was a means to unify the twelve tribes and better defend against Philistine oppression.
The Bible does not detail Saul's genealogy in the context of his right to rule or related to the tenth generation from Perez.
Saul became king around 1020 BCE and led the Hebrews against the Philistines. He was succeeded by King David, indicating that the monarchy's legitimacy was established through leadership and military success rather than strictly by genealogical descent.
Archaeological evidence, such as the Tel Dan stele, supports the existence of a "house of David", but does not provide clarity on Saul's lineage or ruling entitlement.
