Yes. If Rahab was Jesus' biological ancestress, then she was one of His natural connection to Israel. If the Matthew genealogy is Jesus' legal rather than genetic genealogy, then Rahab was one of his legal connections to Israel.
I think that is so cool.
The four eyebrow-raising women of Jesus' genealogy according to Matthew: Tamar, Rahab, Ruth, and Bathsheba. Kind of like "born to be wild."
