Matthew 8:27 - Coke's Commentary on the Holy Bible

The men marvelled, saying, &c.— This reflection, as well as the extreme fear of the disciples in the time of their danger, may seem unaccountable, considering how many and what miracles they had been witnesses to; but both may be explained in some measure by the following remark; that hitherto his miracles were generally upon diseased persons, and that he had given as yet no proofs of his dominion over the elements, the wind and the water, which, it seems, were thought less subject to human power than distempers: or if this does not account for the reflection which the disciples made on seeing the present instance of Christ's power, it may be attributed to the fear and confusion they were in, occasioned by the greatness of their jeopardy, from which they were but just delivered. See more concerning this miracle on Mark 4:37-41.
