Reference: Watches Of The Night
Fausets
The Jews reckoned three military watches: the "first" or beginning of the watches (La 2:19), from sunset to ten o'clock; the second or "middle watch" was from ten until two o'clock (Jg 7:19); the third, "the morning watch," from two to sunrise (Ex 14:24; 1Sa 11:11). Afterward under the Romans they had four watches (Mt 14:25): Lu 12:38, "even, midnight, cockcrowing, and morning" (Mr 13:35); ending respectively at 9 p.m., midnight, 3 a.m., and 6 a.m. (compare Ac 12:4.) Watchmen patrolled the streets (Song 3:3; 5:7; Ps 127:1).
