1 Thessalonians 5:2

5:2 For you know quite well that the day of the Lord ¹  will come in the same way as a thief in the night. ² 

1 Thessalonians 5:28

5:28 The grace of our Lord Jesus Christ be with you. ³ 

[5:2]  ¹ sn The day of the Lord is the period of time in the future when the Lord will intervene in the events of this earth to consummate his redemption and his judgment (Isa 2:11-12; 13:6-13; Ezek 30:3; Joel 1:15; 2:32; 3:18; Amos 5:18-20; Obad 15-17; Zeph 1:7-18; 2:2-3; Zech 14:1, 13, 20-21; Mal 4:1, 5; 1 Cor 1:8; 5:5; 2 Cor 1:14; 2 Thess 2:2; 2 Pet 3:10). It includes both blessings and curses, though the latter is emphasized here.

[5:2]  ² sn Jesus used a thief coming at night as an illustration of the unexpected and hostile nature of the coming of God’s judgment in the future. This is repeated in various ways in v. 4; 2 Pet 3:10; Rev 3:3; 16:15.

[5:28]  ¹ tc Most witnesses, including a few important ones (א A D¹ Ψ 1739^c Ï lat sy bo), conclude this letter with ἀμήν (amhn, “amen”). Such a conclusion is routinely added by scribes to NT books because a few of these books originally had such an ending (cf. Rom 16:27; Gal 6:18; Jude 25). A majority of Greek witnesses have the concluding ἀμήν in every NT book except Acts, James, and 3 John (and even in these books, ἀμήν is found in some witnesses). It is thus a predictable variant. Further, the witnesses for the omission are sufficiently early and diffuse (B D* F G 0278 6 33 1739* 1881 it sa) to render the verdict against the particle here.
