“vigilate ergo (nescitis enim quando dominus domus veniat : sero, an media nocte, an galli cantu, an mane),”
“Watch ye therefore: for ye know not when the master of the house cometh, at even, or at midnight, or at the cockcrowing, or in the morning:”
“Therefore keep watch, because you do not know when the master of the house will return—whether in the evening, at midnight, when the rooster crows, or in the morning.”
“Watch therefore, for you don’t know when the lord of the house is coming, whether at evening, or at midnight, or when the rooster crows, or in the morning;”
“Watch therefore: for ye know not when the lord of the house cometh, whether at even, or at midnight, or at cockcrowing, or in the morning;”
At even, at midnight, or at the cock-crowing, or in the morning. These are generally referred to the different ages of man’s life; infancy, youth, manhood, and old age. We are exhorted to be always in readiness, for we know not at what hour the Judge will come. (Nicholas of Lyra) — We are taught to watch, because we are charged with the care of our soul, which is the temple or house of God, and which is to be his temple for all eternity. (Bible de Vence)
2. We ought to be always upon our watch, in expectation of his return, v. 35-37. (1.) Our Lord will come, and will come as the Master of the house, to take account of his servants, of their work, and of the improvement they have made. (2.) We know not when he will come; and he has very wisely kept us at uncertainty, that we might all be always ready. We know not when he will come, just at what precise time; the Master of the house perhaps will come at even, at nine at night; or it may be at midnight, or a cock-crowing, at three in the morning, or perhaps not until six. This is applicable to his coming to us in particular, at our death, as well as to the general judgment. Our present life is a night, a dark night, compared with the other life; we know not in which watch of the night our Master will come, whether in the days of youth, or middle age, or old age; but, as soon as we are born, we begin to die, and therefore, as soon as we are capable of expecting any thing, we must expect death. (3.) Our great care must be, that, whenever our Lord comes, he do not find us sleeping, secure in ourselves, off our guard, indulging ourselves in ease and sloth, mindless of our work and duty, and thoughtless of our Lord's coming; ready to say, He will not come, and unready to meet him. (4.) His coming will indeed be coming suddenly; it will be a great surprise and terror to those that are careless, and asleep, it will come upon them as a thief in the night. (5.) It is therefore the indispensable duty of all Christ's disciples, to watch, to be awake, and keep awake; "What I say unto you four (v. 37), I say unto all the twelve, or rather to you twelve, I say unto all my disciples and followers; what I say to you of this generation, I say to all that shall believe in men, through your word, in every age, Watch, watch, expect my second coming, prepare for it, that you may be found in peace, without spot, and blameless."
Verses 28-37 We have the application of this prophetic sermon. As to the destruction of Jerusalem, expect it to come very shortly. As to the end of the world, do not inquire when it will come, for of that day and that hour knoweth no man. Christ, as God, could not be ignorant of anything; but the Divine wisdom which dwelt in our Saviour, communicated itself to his human soul according to the Divine pleasure. As to both, our duty is to watch and pray. Our Lord Jesus, when he ascended on high, left something for all his servants to do. We ought to be always upon our watch, in expectation of his return. This applies to Christ's coming to us at our death, as well as to the general judgment. We know not whether our Master will come in the days of youth, or middle age, or old age; but, as soon as we are born, we begin to die, and therefore we must expect death. Our great care must be, that, whenever our Lord comes, he may not find us secure, indulging in ease and sloth, mindless of our work and duty. He says to all, Watch, that you may be found in peace, without spot, and blameless.
