Charles H. Spurgeon on Psalms 119:148

Night watches. The Jews, like the Greeks and Romans, divided the night into military watches instead of hours, each watch representing the period for which sentinels or pickets remained on duty. The proper Jewish reckoning recognized only three such watches, entitled the first, "or beginning of the watches" (Lamentations 2:19), "the middle watch" (Jude 1:7:19), and "the morning watch" (Exodus 14:24; 1 Samuel 11:11). These would last respectively from sunset to 10 p.m.; from 10 p.m. to 2 a.m.; and from 2 a.m. to sunrise. It has been contended by Lightfoot that the Jews really reckoned four watches, three only of which were in the dead of the night, the fourth being in the morning. This, however, is rendered improbable by the use of the term "middle, "and is opposed to Rabbinical authority. Subsequently to establishment of Roman supremacy, the number of watches was increased four which was described either according to their numerical order, as the case of the "fourth watch" (Matthew 14:25), or by the terms" midnight, cock crowing, and morning" (Mark 13:35). These, terminated at 9 p.m., midnight, 3 a.m., and 6 a.m. Conformably to this, the guard of soldiers was divided into four relays (Acts 12:4), showing that the Roman regime was followed in Herod's army. Watchmen appear have patrolled the streets of the Jewish towns (So 3:3 5:7; Psalms 127:1) where for "maketh" we should substitute "watcheth"; Psalms 130:6.
