¹ tn Grk “brothers.” See note on the phrase “brothers and sisters” in 1:4.

² tn Grk “has not become empty.” Paul is defending himself against the charge that he lacked earnestness and personal concern for them, but appeared in their city out of greed or egotism. In his defense he appeals to what they recall of his ministry and what has become of it since he left, all of which demonstrates his God-given earnestness and effectiveness.

³ 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.
