Jewish father determines a Jewish child not a mother. Patrilineal descent was the only recognized linage in Israel. GOD'S Covenant to circumcise Abraham and his SEED established YHWH as his and his SEED'S GOD. Sinai established circumcision as written Law. Children of patriarchal society in Israel were identified by linage of the father. In Rabbinic Judaism matrilineal descent is falsely used to determine Jewishness. An artificial separation between Jewish male circumcision and his GOD YHWH was made. Rabbis stopped male SEED passing on his own Jewishness to his children. But as earth receives SEED, nourishing it until SEED sprouts to become a plant so is woman to SEED of man, she is not the SEED. With Hebrew Bible, genetics and historical documents, proof of how and why Jewish fathers produce Jewish children is shown and that matrilineal descent never existed in any form in Israel. A father always determined the linage, the GOD and Jewishness of his children, male and female.
