Ruth from Moab came to the land of Judah and married Boaz. Ruth and Boaz became the ancestors of David. Rahab from Jericho became a stranger in Israel and married Salmon, the son of the leader of Judah. Rahab and Salmon became the ancestors of Boaz and of David. Both Joseph and Mary, as well as Jesus, descended from David. But if today’s immigration laws had been in effect at the time of Rahab and Ruth, none of these developments could have happened, and there would have been no David, no Mary, and no Jesus.
