{Greatly amazed and sore troubled} (ekthambeisthai kai
ad(886d)onein).  Mt 26:37  has "sorrowful and sore troubled." See on
Matt. about ad(886d)onein. Mark alone uses exthambeisthai (here
and in  9:15 ). There is a papyrus example given by Moulton and
Milligan's _Vocabulary_. The verb 	hambe(935c) occurs in  Mr 10:32 
for the amazement of the disciples at the look of Jesus as he
went toward Jerusalem. Now Jesus himself feels amazement as he
directly faces the struggle in the Garden of Gethsemane. He wins
the victory over himself in Gethsemane and then he can endure the
loss, despising the shame. For the moment he is rather amazed and
homesick for heaven. "Long as He had foreseen the Passion, when
it came clearly into view its terror exceeded His anticipations"
(Swete). "He learned from what he suffered," ( Heb 5:8 ) and this
new experience enriched the human soul of Jesus.
