1 Thessalonians 3:13

3:13 so that your hearts are strengthened in holiness to be blameless before our God and Father at the coming of our Lord Jesus with all his saints. ¹ 

1 Thessalonians 4:16

4:16 For the Lord himself will come down from heaven with a shout of command, with the voice of the archangel, ²  and with the trumpet of God, and the dead in Christ will rise first.

[3:13]  ¹ tc ‡ Important and early witnesses (א* A D* 81 629 lat) have ἀμήν (amhn, “amen”) at the end of this benediction, while the majority of mss, including several excellent witnesses (א² B D² F G Ψ 0278 1739 1881 Ï it sy sa), lack the particle. A decision is difficult, but in light of Paul’s habit of adding the ἀμήν to his notes of praise, even in the middle of his letters (cf. Rom 9:5; 11:36; 15:33; Gal 1:5), one might expect scribes to emulate this practice. Although a decision is difficult, it is probably best to follow the shorter reading. NA²⁷ has the particle in brackets, indicating some doubts as to its authenticity.

[4:16]  ² tn Neither noun in this phrase (ἐν φωνῇ ἀρχαγγέλου, ejn fwnh ajrcangelou, “with the voice of the archangel”) has the article in keeping with Apollonius’ Canon. Since ἀρχάγγελος (ajrcangelo") is most likely monadic, both nouns are translated as definite in keeping with Apollonius’ Corollary (see ExSyn 250-51).
