Well it didn't take God long to get around to mentioning it. Even Christ mentioned the seedlines of the Kenites jn 8.44 and his own back to David.Rev.22.16
Genesis 3:15 "And I will put enmity between thee and the woman, and between thy seed and her Seed; It shall bruise thy head, and thou shalt bruise His heel."
Quite true. Possibly I should have said God doesn’t appear to care much about purity of bloodlines. Belief not blood.
Christ’s own pedigree, for instance, shows that he descended in the direct royal line from Rahab the harlot, Ruth the Moabitess, and two of the most evil women in the whole Bible, Jezebel the Canaanite (Phenician) woman and her daughter Athaliah, who murdered all her son’s children, her own grandchildren, or thought she did, so she could usurp the throne.
There were no doubt many other non-Israelite women in His ancestry that were not mentioned.
