1 Thessalonians 5:2
2. as a thief in the night—The apostles in this image follow the parable of their Lord, expressing how the Lord's coming shall take men by surprise (Mt 24:43; 2Pe 3:10). "The night is wherever there is quiet unconcern" [BENGEL]. "At midnight" (perhaps figurative: to some parts of the earth it will be literal night), Mt 25:6. The thief not only gives no notice of his approach but takes all precaution to prevent the household knowing of it. So the Lord (Re 16:15). Signs will precede the coming, to confirm the patient hope of the watchful believer; but the coming itself shall be sudden at last (Mt 24:32-36; Lu 21:25-32, 35).
2 Peter 3:10
10. The certainty, suddenness, and concomitant effects, of the coming of the day of the Lord. FABER argues from this that the millennium, &c., must precede Christ's literal coming, not follow it. But "the day of the Lord" comprehends the whole series of events, beginning with the pre-millennial advent, and ending with the destruction of the wicked, and final conflagration, and general judgment (which last intervenes between the conflagration and the renovation of the earth).
will—emphatical. But (in spite of the mockers, and notwithstanding the delay) come and be present the day of the Lord SHALL. as a thief—Peter remembers and repeats his Lord's image (Lu 12:39, 41) used in the conversation in which he took a part; so also Paul (1Th 5:2) and John (Re 3:3; 16:15). the heavens—which the scoffers say' shall "continue" as they are (2Pe 3:4; Mt 24:35; Re 21:1). with a great noise—with a rushing noise, like that of a whizzing arrow, or the crash of a devouring flame. elements—the component materials of the world [WAHL]. However, as "the works" in the earth are mentioned separately from "the earth," so it is likely by "elements," mentioned after "the heavens," are meant "the works therein," namely, the sun, moon, and stars (as THEOPHILUS OF ANTIOCH [p. 22, 148, 228]; and JUSTIN MARTYR [Apology, 2.44], use the word "elements"): these, as at creation, so in the destruction of the world, are mentioned [BENGEL]. But as "elements" is not so used in Scripture Greek, perhaps it refers to the component materials of "the heavens," including the heavenly bodies; it clearly belongs to the former clause, "the heavens," not to the following, "the earth," &c. melt—be dissolved, as in 2Pe 3:11. the works . . . therein—of nature and of art.
