2 Peter 2:14 - Matthew Poole's English Annotations on the Holy Bible

Having eyes; he mentions the eyes, both because they let in the objects of lust into the heart, Job 31:1 Matthew 5:28, and because the signs of lust in the heart appear especially in the eyes, Genesis 39:7 Proverbs 6:25. Full of adultery; full of an adulteress, which either may be a Hebraism, the concrete being put for the abstract, as drunken for drunkenness, and thirsty for thirst, Deuteronomy 29:19; or it may be a proverbial expression of the wretchedness of such men's hearts, when they still carried an adulteress in their eyes. That cannot cease from sin; never satisfied with looking upon, or still looking about for, such objects as might inflame their lusts; or still seeking with wanton looks to entice others to folly. Beguiling; either alluring them by their wantonness to embrace their false doctrines, promising them pleasures and carnal liberties, 2 Peter 2:18; or enticing them to lewdness, by instilling false doctrines into them, which tend to licentiousness. Unstable souls; those that were not well grounded in the faith and doctrine of holiness, who might therefore easily be drawn aside. An heart they have exercised with covetous practices; a heart wholly intent upon getting gain, accustomed to it, and skilful in it. Practices; the word is in the plural number, to show that the seducers had several arts and ways of exercising their covetousness. Cursed children; Greek, children of the curse. It may be taken either actively, for such as were causes of a curse, brought a curse with them; or passively, for such as were worthy of a curse, or obnoxious to it; as children of wrath, Ephesians 2:3.
