Matthew Poole and continuators on Jude 1:13

13 Raging waves of the sea foaming out their own shame : wandring stars , to whom is reserved the blackness of darkness for ever.

Not only inconstant as Water, but unquiet, t[illegible: 4 letters]lent, restless, that cannot cease from Sin.

That wickedness whereof they should be ashamed: like a troubled Sea, when it cannot rest, whose Waves cast out Mire and Dirt, Isa. 57.20.

Either Planets properly called, or rather Meteors called running Stars, inconstant in their motion, uncertain in their shining, making a little shew, but presently vanishing; such was the Doctrine of these, which had a shew of Light, but a deceitful and unconstant one.

The thickest Darkness, viz. that of Hell; they would be counted Lights, but are themselves cast into utter Darkness, 2 Pet. 2.17. As blackness of Darkness shews the horror of their Punishment, so its being reserved for them shews the certainty of it.
