Musar su Salmi 108:10

You should know further that the wicked Bilaam gathered all types of herbs for use in his sorcery and then put them in a pot, which he buried deep in the earth, fifteen hundred cubits underground. Years later when Dovid HaMelech was excavating holes on the site of the Temple to bring up ground water for use in the libations on the altar, holes that were also fifteen hundred cubits deep, he came across the pot that Bilaam had buried. He then removed it and diluted it with water that was fit for the libations. Concerning this was it written, “Moav is my wash basin” (Tehillim 108:10), for he “washed” it and removed the power of sorcery that was in Moav’s pot. Therefore whenever there is suspicion of harm due to sorcery it is a good strategy to neutralize it by reciting the fifteen “Songs of Ascent” (Tehillim 120-135), which Dovid composed at the time that he excavated those holes to bring up the groundwater (Sukkah 53a). Afterwards let them pray to Hashem to remove from Israel all the harm caused by sorcery. It is also advisable for every Jewish man and woman to stay as far away from sorcery as possible. Let them avoid all acts of sorcery, augury and divination and let them avoid hearing the recitation of any incantation. For the Holy One Blessed is He takes pride in His people that, “There is no augury among Yaakov and no divination among Yisroel” (Bamidbar 23:23). Whoever stays far from sorcery will be allowed to enter a partition in the World to Come within which even the ministering angels cannot stand (Nedarim 32a).
