358. Two female spirits used to come and couple with him and they gave birth. They gave birth to demons called the plagues of mankind. They would fly to people and rest at their doors, wells and restrooms. Therefore all DEMONS flee and distance themselves from people who have on their door posts the holy name Shadai of the supernal Sfirot. This is the essence of the verse, "Nor shall any plague come near your dwelling" (Tehilim 91:10). What is meant by "nor shall any plague come near?" It is the MENTIONED plagues of people.
