2 Thessalonians 3:17-18 New English Translation

¹⁷I, Paul, write this greeting with my own hand, which is how I write in every letter.^[a] ¹⁸The grace of our Lord Jesus Christ be with you all.^[b]

2 Thessalonians 3:17 tn Grk “The greeting in my hand, Paul, which is a sign in every letter, thus I write.”sn Up to 3:17 the letter was dictated by Paul but written down by a secretary or amanuensis. But Paul took up the pen and wrote vv. 17-18 personally to authenticate that it was his (how I write in every letter). See similar indications in 1 Cor 16:21; Gal 6:11; and Col 4:18.
2 Thessalonians 3:18 tc Most witnesses, including some early and significant ones (א² A D F G Ψ 1175 1241 1505 1881^c M lat sy bo), conclude this letter with ἀμήν (amēn, “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 among the best mss (א* B 0278 6 33 1739 1881* 2464 sa), giving sufficient base to prefer the shorter reading.
