For the one who said, “Do not commit adultery,” also said, “Do not commit murder.” Now if you do not commit adultery but do commit murder, you have become a transgressor of the Torah.
“Now if the whole congregation of Israel sins, but the deed is hidden from the eyes of the community, yet they have done one of Adonai’s mitzvot that are not to be done, then they are guilty.
You know the commandments, ‘Do not murder, do not commit adultery, do not steal, do not give false testimony,’ do not cheat, ‘honor your father and mother.’”
For the commandments—“You shall not commit adultery, you shall not murder, you shall not steal, you shall not covet,” and any other commandment—are summed up in this word: “You shall love your neighbor as yourself.”
