Justin Martyr

But as there the prophet says, 'And now, O house of Jacob, come and let us walk in the light of the Lord; for He has sent away His people, the house of Jacob, because their land was full, as at the first, of soothsayers and divinations;' even so it is necessary for us here to observe that there are two seeds of Judah, and two races, as there are two houses of Jacob: the one begotten by blood and flesh, the other by faith and the Spirit.
