1 Thessalonians 3:13 New English Translation

¹³so 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.^[a]

1 Thessalonians 3:13 tc ‡ Significant and early witnesses (א* A D* 81 629 lat bo) have ἀμήν (amēn, “amen”) at the end of this benediction, while the majority of mss, including several excellent authorities (א² B D² F G Ψ 0278 1175 1241 1505 1739 1881 2464 M 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, since there is little reason for scribes to omit the particle, it is best to follow the shorter reading. NA²⁸ has the particle in brackets, indicating some doubts as to its authenticity.
