Matthew 24:42

“Therefore stay alert, because you do not know on what day ¹  your Lord will come.

Mt 24:36,44; Mt 25:13; Mt 26:38-41; Mr 13:33-37; Mr 13:33; Lu 12:35-40; Lu 21:36; Ro 13:11; 1Co 16:13; 1Th 5:6; 1Pe 4:7; 1Pe 5:8; Re 3:2,3; Re 16:15

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.
