The smoke of their torment (o kapno tou basanismou autwn). See Ezekiel 9:5 for basanismo, only there it was a limited penalty, here it is "for ever and ever" (ei aiwna aiwnwn, unto ages of ages). See also Ezekiel 18:9 ; Ezekiel 19:3 ; Ezekiel 20:10 . They have no rest (ouk ecousin anapausin). The very language used in Ezekiel 4:8 of the four living creatures in praising God. "Those who desert Christ for Caesar will be the victims of a remorse that never dies or sleeps" (Swete). The rest of the verse repeats the solemn challenge of verse Ezekiel 9 .
