Luke 9:32

Now Peter and they that were with him were heavy with sleep: but when they were fully awake, they saw his glory, and the two men that stood with him.

This is the evangelist Luke's categorical denial that it was any such thing as a dream, or vision, which the holy apostles saw. Childer's comment that "Peter, James and John slept through a part of the happenings,"[5] is not correct. "When they were fully awake" has the alternate reading, "having remained awake" (English Revised Version (1885) margin); and Luke's clear intent is to affirm their remaining awake, despite the fact of their being sleepy.
