¹ tc Most later mss (L 0281 Ï lat) have here ὥρᾳ ({wra, “hour”) instead of ἡμέρα (Jemera, “day”). Although the merits of this reading could be argued either way, in light of the overwhelming and diverse early support for ἡμέρᾳ ({א B C D W Δ Θ Ë¹³ 33 892 1424, as well as several versions and fathers}), the more general term is surely correct.

² tc Most later mss (C³ ˹³ 1424^c Ï) also read here “in which the Son of Man is coming” (ἐν ᾗ ὁ υἱὸς τοῦ ἀνθρώπου ἔρχεται, en |h Jo Juio" tou anqrwpou ercetai), reproducing almost verbatim the last line of Matt 24:44. The longer reading thus appears to be an explanatory expansion and should not be considered authentic. The earlier and better witnesses ({̳⁵ א A B C* D L W Δ Θ Ë¹ 33 565 892 1424* lat co}) lack this phrase.
