Jude 1:6
And the angels who did not keep their proper domain but abandoned their correct dwelling place—these he has kept in darkness, bound with everlasting chains for judgment on the great Day — Jude references the Enochian tradition (likely from 1 Enoch 12-16) concerning the 'watchers,' angels who abandoned their appointed sphere of authority and engaged in sexual union with human women, begetting the Nephilim. The punishment—eternal chains in darkness—demonstrates God's willingness to judge even the highest orders of creation when they transgress their boundaries, establishing a precedent for judging human apostates who likewise violate proper order. The eschatological framing ('for judgment on the great Day') situates this punishment within God's larger plan of cosmic vindication.
