In the Gospel, Beelzebub is ‘the prince of devils’, virtually the same as ‘Satan’. The word is of limited occurrence in the Bible and may have been a local word in the area of Galilee.
In 1954 there appeared a novel by the English novelist, William Golding, describing how a party of school-children stranded on a desert island quickly lose their veneer of civilisation and descend into savagery and blood-lust. The novel directs a counter-blast against conventional notions of the innocence of childhood. The title of the novel is ‘Lord of the Flies’, and this is the usual English translation of the word ‘Beelzebub’.
