Commentaries:
Robertson's Word Pictures (NT)
Hidden rocks (spiladev). Old word for rocks in the sea (covered by the water), as in Homer, here only in N.T. II Peter 2:13 has spiloi.
Love-feasts (agapaiv). Undoubtedly the correct text here, though A C have apataiv as in II Peter 2:14. For disorder at the Lord's Supper (and love-feasts?) see 1Co. 11:17-34. The Gnostics made it worse, so that the love-feasts were discontinued.
When they feast with you (suneuwxoumenoi). See II Peter 2:13 for this very word and form. Masculine gender with outoi oi rather than with the feminine spiladev. Cf. Revelation 11:4. Construction according to sense.
Shepherds that feed themselves (eautouv poimainontev). "Shepherding themselves." Cf. Revelation 7:17 for this use of poimainw. Clouds without water (nefelai anudroi). Nefelh common word for cloud (Matthew 24:30). II Peter 2:17 has phgai anudroi (springs without water) and then omixlai (mists) and elaunomenai (driven) rather than periferomenai here (borne around, whirled around, present passive participle of periferw to bear around), a powerful picture of disappointed hopes.
Autumn trees (dendra fqinopwrina). Late adjective (Aristotle, Polybius, Strabo) from fqinw, to waste away, and opwra, autumn, here only in N.T. For akarpa (without fruit) see II Peter 1:8.
Twice dead (div apoqanonta). Second aorist active participle of apoqnhskw. Fruitless and having died. Having died and also "uprooted" (ekrizwqenta). First aorist passive participle of ekrizow, late compound, to root out, to pluck up by the roots, as in Matthew 13:29.
