"In the Bible three of the Ten Commandments deal specifically with this matter: do not covet another man’s wife, do not commit adultery, and honor mother and father; the last is the first “substantial” commandment that doesn’t directly involve honoring God but that concerns human behavior as such, and for this reason among others Nietzsche believed it was the constitutive goal of the Hebrews, the striving that defined them as a people. In Judaism during the holiest day of Yom Kippur the prohibition specifically against incest at Leviticus 18 is traditionally repeated, which, as Leo Strauss mentions, agreeing with Nietzsche, is the precondition for honoring mother and father. But the language of Leviticus 18 with its list of sexual prohibitions is especially powerful, contrasting the new laws of the Hebrews with those of the Egyptians and with others who came before them, who defiled the land, and who were vomited out by the land."
