John Chrysostom — as excerpted in the Catena Aurea on John 11:11-16

“(Hom. lxii. 2.) But if any one say, that the disciples could not but have known that our Lord meant Lazarus’s death, when He said, that I may awake him; because it would have been absurd to have gone such a distance merely to awake Lazarus out of sleep; we answer, that our Lord’s words were a kind of enigma to the disciples, here as elsewhere often.”
