And in the fourth watch of the night,.... This is said, according to the division of the night into four watches, by the Jews; who say, that"there are four watches in the night, and four watches in the day.'
'It is true indeed, that it is disputed among them, whether there were four watches, or only three in the night: some say there were four, others say there were but three ; not but that these made a division of the night into four parts, the three first of which, they thought were properly the watches of the night, and the fourth was the morning.
The first watch began at six o'clock in the evening, and lasted till nine; the second began at nine, and ended at twelve, which was midnight; the third began at twelve, and closed at three; the fourth began at three, and ended at six in the morning.
But since some Jewish writers are so positive for the division of the night into three watches only, and a watch is with them called the third part of the night; and it is dubious with some, whether the Jewish division is here referred to; and since it is so clear a point, that the Romans divided their night into four watches, and their writers speak not only of the first, second, and third watches, but also of the fourth watch ; it is thought by some, that the evangelist speaks after the Roman manner: but however, certain it is, that within this period, probably at the beginning of it, after three o'clock in the morning, Christ came to his disciples, when they had been almost all the night at sea, tossed with waves, and in great danger.
