Jamieson, Fausset and Brown on 2 Peter 2:11

11. which are--though they are.

greater--than these blasphemers. Jude instances Michael (Jude 9).

railing accusation--Greek, "blaspheming judgment" (Jude 9).

against them--against "dignities," as for instance, the fallen angels: once exalted, and still retaining traces of their former power and glory.

before the Lord--In the presence of the Lord, the Judge, in reverence, they abstain from judgment [Bengel]. Judgment belongs to God, not the angels. How great is the dignity of the saints who, as Christ's assessors, shall hereafter judge angels! Meanwhile, railing judgments, though spoken with truth, against dignities, as being uttered irreverently, are of the nature of "blasphemies" (Greek, 1Co 4:4, 5). If superior angels dare not, as being in the presence of God, the Judge, speak evil even of the bad angels, how awful the presumption of those who speak evil blasphemously of good "dignities." 2Sa 16:7, 8, Shimei; Nu 16:2, 3, Korah, &c., referred to also in Jude 11; Nu 12:8, "Were ye (Aaron and Miriam) not afraid to speak evil of My servant Moses?" The angels who sinned still retain the indelible impress of majesty. Satan is still "a strong man": "prince of this world"; and under him are "principalities, powers, rulers of the darkness of this world." We are to avoid irreverence in regard to them, not on their account, but on account of God. A warning to those who use Satan's name irreverently and in blasphemy. "When the ungodly curseth Satan, he curseth his own soul."
