[2:5]  ¹ tn Grk “Have this attitude in/among yourselves which also [was] in Christ Jesus,” or “Have this attitude in/among yourselves which [you] also [have] in Christ Jesus.”

[4:13]  ¹ tn The Greek word translated “all things” is in emphatic position at the beginning of the Greek sentence.

[4:13]  ² tc Although some excellent witnesses lack explicit reference to the one strengthening Paul (so א* A B D* I 33 1739 lat co Cl), the majority of witnesses (א² D² [F G] Ψ 075 1881 Ï sy) add Χριστῷ (Cristw) here (thus, “through Christ who strengthens me”). But this kind of reading is patently secondary, and is a predictable variant. Further, the shorter reading is much harder, for it leaves the agent unspecified.

[4:23]  ¹ tc Most witnesses, including several important ones (Ì⁴⁶ א A D Ψ 33 Ï lat sy bo), have ἀμήν (amhn, “amen”) at the end of this letter, while an impressive combination of Alexandrian and Western mss (B F G 075 6 1739* 1881 sa) lack the valedictory particle. 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. Thus, on internal grounds, with sufficient support from external evidence, the preferred reading is the omission of ἀμήν.
