"Law of the Gentiles: Continuum or Contrast?This is very puzzling. If G-d never revealed His Instructions to mankind, how did Adam and Eve know to teach their children about sacrifices? If there is nothing to be learned from Gentile religions, why did Moses accept Jethro's teaching in Exodus 18? If G-d never revealed His Law to gentile nations, why did G-d judge the gentiles of Noah's era for their lawlessness? Etc, etc.
'He issues His commands to Jacob, His statutes and rules to Israel. He did not do so for any other nation; of such rules they know nothing. Hallelujah' (Psalms 147:19-20). This may sound like a rather extreme statement; but let us recall that even though the Bible expects moral behavior of all people (and not only Jews), it nowhere asserts that God revealed His law to any but Jews. The Sages, of course, would have to square these verses in Psalms with the belief in Noahide Law that is commanded to all men," Schacter, Judaism's Encounter with Other Cultures, pg. 27
Does anyone have any thoughts?
