When Moshe led the Jewish people, there came a time where he spoke with Hashem and asked for him to relieve his burden. He needed help with the responsibility that had been placed upon him.
This led to the 70 elders being gathered who would all share in the burden so Moshe wouldn't have to carry it alone.
Where did a king fit into any of this and wouldn't a king have been problematic from the Jewish perspective?
The Sanhedrin existed as a series of councils which dealt with everyday matters and deeper religious matters.
In theory, we could have existed entirely independent from kings/royalty and Jewish society would have functioned through the guidance of the Rabbis.
Here is where the question ultimately comes from.
Kings can be inherently problematic. If you look at the history of monarchies in Europe, you see that kings place themselves as being equal to the authority of god in a certain respect. The idea being that god made them king so gods authority is his authority.
We saw this go down with King James and the church of England.
We even saw how the politics of the situation could damage the structure of society. Specifically, the divide that occurred between Judah and the Northern Kingdom.
My question is why was a king necessary? Didn't the Jewish people have structures in place which could have met the everyday functions of Jewish society?
