Bible: Rev. 13:18, 17
13:18 This calls for wisdom: 1 Let the one who has insight calculate the beast’s number, for it is man’s number, 2 and his number is 666. 3 13:17 Thus no one was allowed to buy 4 or sell things 5 unless he bore 6 the mark of the beast – that is, his name or his number. 7 NET Bible Study Environment
