“The Ways of the Emorite”

 https://outorah.org/p/20491/

 The Beit Yosef (YD 178) explains in the name of the SeMaG, that the cryptic expression "the ways of the Emorite" comprises two distinct prohibitions. One is the prohibition against sorcery, which was apparently widespread among the Emorites; the other is the general prohibition for Jews to gratuitously imitate other nations, as commanded in the verse "And don't walk in their ways" (Vayikra 18:3).
