Matthew 14:25

25. Fourth watch of the night A watch is the regular period which a soldier or sentinel keeps guard by night before he is relieved by a successor. The ancient Jewish watches were three a night, the middle being at midnight. But just before Matthew wrote, the Jews had adopted the Roman custom of four watches of three hours each. These watches began at six, nine, twelve, and three, so that it was about three in the morning that our Lord made himself visible to his disciples. The disciples, starting from Butaiha toward Bethsaida, had toiled in rowing from eve until near morning, and had made but a little more than three miles from their starting place, having been driven southward, below the route to Capernaum, in the direction of the plain of Gennesaret. At three of the morning the dim form of Jesus walking upon the surface of the heaving billows is descried by the disciples in the ship. Stier eloquently says:

“What is that? they ask among themselves in terror; and the fear which now first breaks out in earnest, precisely when the helper comes, answers, It is an apparition, a phantasm; and when the terrifying word is spoken they cry out for fear. Is it a welcome from the Sheol, to which they fancy they are now near? This it cannot be, for the thing upon the sea assuredly looks like the Lord. It is more likely, therefore, to occur to them, that their excited imagination now morbidly deludes them with the figure of Him who has been so much in their thoughts if, indeed, they have any definite idea at all of this phantasm. Man, in his present state, in the fear and perplexity of spirit which may so easily overtake him, sees apparitions; and takes even his Saviour, as he draws nigh in divine power, at first to be such. This, however, is always better than, in the opposite folly of boldness, to take a phantasm of his own thoughts as the Lord and Saviour.”
