Augustine of Hippo

(de Cons. Ev. iii. 4.) This speech as Matthew has it seems self-contradictory. For how could He say, Sleep on, and take your rest, and immediately continue, Rise, let us be going. This contradiction some have endeavoured to reconcile by supposing the words, Sleep on, and take your rest, to be an ironical rebuke, and not a permission; it might be rightly so taken if need were. But as Mark records it, when He had said, Sleep on, and take your rest, He added, it is enough, and then continued, The hour is come, behold, the Son of man is betrayed into the hands of sinners; (Mark 14:41.) we clearly understand the Lord to have been silent some time after He had said, Sleep on, to allow of their doing so, and then after some interval to have roused them with, Behold, the hour is at hand. And as Mark fills up the sense with, it is enough, that is, ye have had rest enough.
