Gevurot 16:16-18 Orthodox Jewish Bible (OJB)
16 And it came about when we were going to where they held the minyan, that a certain shifchah having a ruach of the python (i.e., a shed, demon) came out to meet us. She was bringing much profit to her adonim by divination. [Dt 18:11; 1Sm 28:3,7]
17 This one was following Rav Sha’ul, crying out, saying, "These anashim are avadim of G-d HaElyon and are proclaiming to you the Derech HaYeshu’at Eloheinu."
18 And this kviusdik thing she was doing for many yamim; but Rav Sha’ul, whom she wouldn’t stop derkutshen, turned to the ruach, and said, "I command you in haShem of Rebbe, Melech HaMoshiach Yehoshua to come out from her!” And it came out in the same hour.
