The Zohar, the 'bible of the Kabbalah' - states Jews
must sacrifice a goat to Satan every new moon.
"Come and see: Every single new moon, as the moon is renewed, this End of all flesh is given one portion over and above the offerings, to keep him occupied handling his portion, so that the aspect of Israel is alone to delight with their King. This is the goat (According to Numbers 28:15, on each new moon a goat must be brought as a sin-offering. Here, this goat is intended to preoccupy Satan, leaving Israel alone with God.)" Zohar 1:65a
"224. goat of the new moon... According to Numbers 28:15, on each new moon a goat must be brought as a sin-offering. Here, this goat too is intended to preoccupy Satan, leaving Israel and Shekhinah (both symbolized by the moon) alone with the blessed Holy One." source
