tc The reading “all this time” (πάλαι, palai) is found in several early and important Alexandrian and Western witnesses including א* A B F G 0243 6 33 81 365 1175 1739 1881 lat; the reading πάλιν (palin, “again”) is read by א2 D Ψ 0278 𝔐 sy bo; the reading οὐ πάλαι (ou palai) is read by 𝔓46, making the question even more emphatic. The reading of 𝔓46 could only have arisen from πάλαι. The reading πάλιν is significantly easier (“are you once again thinking that we are defending ourselves?”), for it softens Paul’s tone considerably. It thus seems to be a motivated reading and cannot easily explain the rise of πάλαι. Further, πάλαι has considerable support in the Alexandrian and Western witnesses, rendering it virtually certain as the original wording here.

tn Or “for your strengthening”; Grk “for your edification.”
