2:10-16 Impure seducers and their abandoned followers, give themselves up to their own fleshly minds. Refusing to bring every thought to the obedience of Christ, they act against God's righteous precepts. They walk after the flesh, they go on in sinful courses, and increase to greater degrees of impurity and wickedness. They also despise those whom God has set in authority over them, and requires them to honour. Outward temporal good things are the wages sinners expect and promise themselves. And none have more cause to tremble, than those who are bold to gratify their sinful lusts, by presuming on the Divine grace and mercy. Many such there have been, and are, who speak lightly of the restraints of God's law, and deem themselves freed from obligations to obey it. Let Christians stand at a distance from such.

14. full of adultery—literally, "full of an adulteress," as though they carried about adulteresses always dwelling in their eyes: the eye being the avenue of lust [Horneius]. Bengel makes the adulteress who fills their eyes, to be "alluring desire."

that cannot cease—"that cannot be made to cease from sin."

beguiling—"laying baits for."

unstable—not firmly established in faith and piety.

heart—not only the eyes, which are the channel, but the heart, the fountain head of lust. Job 31:7, "Mine heart walked after mine eyes."

covetous practices—The oldest manuscripts read singular, "covetousness."

cursed children—rather as Greek, "children of curse," that is, devoted to the curse. Cursing and covetousness, as in Balaam's case, often go together: the curse he designed for Israel fell on Israel's foes and on himself. True believers bless, and curse not, and so are blessed.
