{That have no law} (	a m(8820)nomon echonta). Better, "that
have not the law" (the Mosaic law). {By nature} (phusei).
Instrumental case of phusis, old word from phu(935c), to beget.
The Gentiles are without the Mosaic law, but not without some
knowledge of God in conscience and when they do right "they are a
law to themselves" (heautois eisin nomos). This is an obvious
reply to the Jewish critic.
