Midrash su Salmi 107:26

Rabba b. b. Chana said again: "I have seen Hurmin bar Lilith (night demon) jumping on the top of brick-houses of the city of Mechuza and was running so fast from one to the other that a rider who was on horseback below could not overtake him. Once it happened that two mules were saddled for him on the two bridges over the River Ravg'nag (Ib. b). Although they were far from each other, he jumped continually from one saddle to the other, while holding two cups of wine, pouring from one into the other continually without spilling one drop, yet this day was such a stormy one, as illustrated (Ps. 107, 26) They would mount up to heaven, they would go down to the depths. Later the government took notice of him, and he was executed."
