Theophylact of Ohrid — as excerpted in the Catena Aurea on John 11:6-10

“Some understand the day to be the time preceding the Passion, the night to be the Passion. In this sense, while it is day, would mean, before My Passion; Ye will not stumble before My Passion, because the Jews will not persecute you; but when the night, i. e. My Passion, cometh, then shall ye be beset with darkness and difficulties.”
