Hath his sword upon his thigh; is prepared and ready to fight, as this phrase notes, Exodus 32:27 Psalms 45:3. Because of fear in the night; to prevent those dangers and mischiefs which are most frequent and most dreadful in the night season. The night may note either,
1. The time of tribulation, temptation, or desertion. Or,
2. The whole time of this life, which may well be called night, in respect of that ignorance, and error, and other kinds of darkness wherewith it is attended, as the future life is compared to a day, this life being the only time wherein such a guard is necessary.
