What does any of this have to do with the topic at hand?
Because I'm reading a LOT of things people are saying that is not in line with what scriptures are saying.
An isolated verse may appear to say something different from the truth.
Especially with parentage. Because in Hebrew there is no word for grandfather or even forefather. (Same with the feminine)
And since names are action word titles sometimes synonyms are used. Or in the case of Jacob/Israel there are two names/titles associated with the same person.
In the 51st Psalm David says he was conceived and born in sin.
It's a poetic way (hyperbole) of David claiming to be very wrong. It does not mean he was an illegitimate child born out of wedlock. The story of Ruth is all about the kinsman redeemer and a daughter-in-law that was extremely faithful to her mother-in-law.
It's a wonderful story.
The tribe of Judah, during the time of Jesse, was disappearing....evaporating away. It was the smallest tribe in numbers at that point. Not the largest as the movie keeps claiming.
It became the largest AFTER David ascended to the throne.
This was due to David's family and David's many wives having children.
