{They feared exceedingly} (ephob(8874)h(8873)an phobon megan).
Cognate accusative with the first aorist passive indicative. They
feared a great fear.  Mt 8:27  and  Lu 8:22  mention that "they
marvelled." But there was fear in it also. {Who then is this?}
(Tis ara houtos estin;). No wonder that they feared if this One
could command the wind and the waves at will as well as demons
and drive out all diseases and speak such mysteries in parables.
They were growing in their apprehension and comprehension of
Jesus Christ. They had much yet to learn. There is much yet for
us today to learn or seek to grow in the knowledge of our Lord
Jesus Christ. This incident opened the eyes and minds of the
disciples to the majesty of Jesus.
