I recently tried to research a question I had: "Why does the gospel of Matthew consider Jesus Christ to be a descendant of David even though Joseph was not his biological father?" Apparently in Judaic tradition back then, the legal father of a child was considered a father even if there is no blood relation. I'm wondering if that's true. But additionally, many people claimed that Mary his mother was a blood descendant of King David. Is there anything in scripture that supports this suggestion?
I tried researching this and I'm a tad confused. Someone pointed to the genealogy in Luke 3:23 in support of this claim, saying that though Joseph is listed in Luke's genealogy as the son of Heli that that is only because Joseph was head of the household. I think that's what they're trying to say. So is Mary in actuality the blood descendent of Heli and thus a blood descendant of King David?
Luke 3:23 states: “And Jesus himself began to be about thirty years of age, being (as was supposed) the son of Joseph, which was the son of Heli.” Since Joseph was head of household, he was listed in Luke as the son of Heli rather than Mary being listed as the daughter of Heli. Therefore, Mary was also from the house and lineage of David since she descended from David’s son Nathan. Also, I'm wondering if Heli is the name of a man or woman.
Additionally, it would appear that Joseph is the descendant of King David's son Solomon and Mary a descendant of King David's son Nathan. I'm wondering if that's the case or if I'm just confused here.
