Abahin is a demon appearing in Mathers' translation of the Sacred Magic of Abramelin the Mage. He along with many other demon spirits serves the arch-fiends Astaroth and Asmodeus. This demon's name comes from a Hebrew root word meaning "the Terrible One." Another Abramelin edition originally written in code and housed in the library in Wolfenbuttel, Germany has the name Ahabhon. A.G.H.
