William Henry Bennett, 1911 Encyclopædia Britannica (1910)
“ In the New Testament we meet with Beelzebul, [7] which some of the versions, especially the Vulgate and Syriac, followed by the Authorized Version, have changed to Beelzebub, under the influence of 2 Kings. In Matt. x. 25, Christ speaks of men calling the master of the house, i.e. Himself, Beelzebul. [8] In Mark iii 22-27, [9] the scribes explain that Jesus is possessed by Beelzebul [10] and is thus enabled to cast out devils. The passage speaks of Beelzebul as Satan and as the prince of the demons. ”
