Judas 1:13

'Wild waves of the sea, casting up the foam of their own shame; wandering stars, for whom the gloom of utter darkness has been reserved forever' — Jude's catalogue of apostasy employs natural imagery of violent disorder (Jude 1:12–13) drawn from Isaiah 57:20 ('the wicked are like the tossing sea') and 1 Enoch 18:14–16 (wandering stars as fallen angels). The 'foam of shame' (epaphrizonta tas heautōn aischynas) evokes the spectacle of a shoreline covered in detritus — public display of what the false teachers try to conceal is the prophetic irony. 'Wandering stars' in Second Temple Jewish cosmology referred to planets that followed irregular paths, associated with fallen angelic beings whose ordained courses had been abandoned — a fitting image for teachers who have deviated from their proper calling. The image of 'gloom of utter darkness reserved forever' draws on the Jewish apocalyptic tradition of the netherworld as dark prison (1 Enoch 21; 2 Peter 2:17), framing the false teachers' destiny as cosmically ordained.
