Vayikra: Chapter 38
"A complainer separates close friends"

Rabbi Shimon opens with, "A perverse man sows strife: and a whisperer separates close friends." He says that evil men cause a blemish above because they separate men from God and male from female and Zeir Anpin from Malchut. He causes the plants to nourish from the side of Judgment. Rabbi Shimon says that the penitent stands in a higher place than the wholly righteous, because the penitent draws abundance down to the place of the righteous, and the righteous draw it down to the world. He also talks about the loss of faithfulness.
