In the Jewish religion, heritage is the upmost importance. The 1st chapter of Matthew is listed the lineage of Jesus. One, it is to prove that He is Jewish and two, it’s to see His family. The linage comes from the father, but being Jewish comes from His mother. In Jesus’s family, there is a king, 2 prostitutes, and Moabitess. Moab, brother to Israel, was cursed by God and no wives could be taken from them. Read the book of Ruth. God isn’t willing that any should perish, but all should come to the saving knowledge of Christ. Apostle Paul said it himself, I am the chiefest of sinners. God made a covenant with Abraham. God was fulfilling He promise and sent His son to redeem man. And the birth of Jesus was on this wise.
