Why did priests flay victims and then wear the skin for 20 days?

Priests flayed victims and wore their skin as part of ritualistic practices, often linked to religious beliefs about sacrifice and the appeasement of deities. This gruesome act was thought to invoke divine favor, enhance the priest's spiritual power, or symbolize the connection between the divine and the mortal realm. The 20-day period likely held specific cultural or religious significance, representing a time of mourning, purification, or transformation. Such practices reflect the complex interplay between ritual, power, and belief in certain ancient cultures.
