Ver. 38.—And if He shall come in the second watch, and if in the third, and find them so, blessed are those servants. The first watch begins in the evening at the beginning of night, and lasts three hours. The second then begins and lasts till midnight. Then follows the third, which also lasts for three hours; then the fourth, which lasts till the dawn and the rising of the sun. Christ shows by these watches when we ought to watch and be prepared for the coming of the Lord; for the time of our death is uncertain, nor have we one day or even hour of our life of which we can be sure. The first watch is our childhood, the second our youth, the third our grown manhood, the fourth, our old age. So Titus and S. Gregory. “Christ does not,” says F. Lucas, “mention so much the fourth and first watches, because He does not often come from the marriage so early or so late. The marriages are generally concluded about the middle of the night when the bride is conducted to the marriage chamber. Meanwhile, it teaches us that we ought always to watch even in advanced age and decrepitude, and that it is not enough to watch only for a time, or in youth, or in manhood, but we must persevere as long as this life lasts, because the hour of our death is uncertain, and also the coming of our Lord, even though He be long waited for.” So S. Basil in his homily of not regarding secular affairs: “We ought to be prepared daily to depart from this life and to await the unchanged nod of God, that each, when the Lord comes and knocks, may immediately open to Him. Christ, besides, speaks only of the second and third watch, because sleep in them is deeper and more heavy, to show that He would come when men least expected Him; when they were sunk in profound thoughts and cares, and, as it were, were asleep; so that wise servants should then most especially watch and be prepared, that when they seem to themselves most healthful and prosperous they may look for a sudden and treacherous death.”

Toletus gives another reason. “Christ,” he says, “does not make mention of the fourth watch because there are very few, who, having put off good works till old age, are then found to be doing them; and He might have made them tardy if He had spoken of the matter.” From this S. Gregory concludes (Hom. 13), exhorting all men to holy lives, and saying, “Our Lord would not reveal the last hour to us, that it might always be looked for, and whilst we are not able to foresee it, that we should without cessation be prepared for it.” Because then the hours fly apace, be careful, O most dear brethren, to be occupied with the traffic of good works. Hear what wise Solomon said: “Whatsoever thy hand findeth to do, do it with thy might, for there is no work, nor device, nor knowledge, nor wisdom in the grave whither thou goest.” Because then we know not the time of our death, and cannot work after it, we ought to seize the time allowed us before its arrival. Thus, by our being always in fear of it will death itself be vanquished.
