1 Thessalonians 3:12-13

3:12 And may the Lord cause you to increase and abound in love for one another and for all, just as we do for you, 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 

[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.
