Watch, therefore - This is the scope or design of the whole parable. This is the great truth that Christ wished to inculcate, and all parts of the parable are to be interpreted in reference to this admonition. Like the virgins, many are professedly going to meet the Bridegroom - the Lord Jesus Christ. Like the coming of the bridegroom, his advent will be sudden. It will be to many at an unexpected time. Many, even professing Christians, will be engaged in the business of the world; thoughtless about eternity; not expecting his approach, and not prepared. They will only profess to know him, but in works they will deny him. So death will come. All approaches of the Son of God to judge men are sudden, and to many unexpected. So many, when they shall see him coming, at death or the judgment, will begin, like the foolish virgins, to be active, and to prepare to die; but it will be too late. They that are ready will enter in, and heaven will be closed forever against all others. The "coming" of the Saviour is certain. The precise time "when" he will come is not certain. As the virgins should all have watched and been ready, so should we. They who are Christians should be ever watchful; and they who are not should lose no time to be ready, for in such an hour as they think not the Son of man shall come.
The Son of man cometh - This refers, doubtless, to his coming in the day of judgment. The circumstances of the parable do not seem at all to apply to his coming to destroy Jerusalem, but are aptly expressive of his advent to judge the world.

Watch therefore - If to watch be to employ ourselves chiefly about the business of our salvation, alas! how few of those who are called Christians are there who do watch! How many who slumber! How many who are asleep! How many seized with a lethargy! How many quite dead!
Wherein the Son of man cometh - These words are omitted by many excellent MSS., most of the versions, and several of the fathers. Griesbach has left them out of the text: Grotius, Hammond, Mill, and Bengel, approve of the omission.

Watch therefore,.... In ordinances, in prayer, public and private, in hearing the word, at the Lord's supper, and in every religious exercise; over the heart, the thoughts and affections of it; over words, actions, life, and conversation; and against all sin and unbelief, Satan's temptations, the world, and its charms and snares, false teachers, and their doctrines, and for the bridegroom's coming. This is the use and application of the whole parable, and shows the general design of it; the reason to enforce watchfulness follows:
for ye know neither the day nor the hour; of death, or of judgment, or of the coming of the son of man, of one or the other; for it is added,
wherein the son of man cometh: that he will come is certain, and that quickly; the time is fixed, but when it will be is unknown; and therefore it becomes us to be our watch and guard. This last clause is not in the Vulgate Latin, nor in the Syriac, Arabic, Persic, and Ethiopic versions, and was wanting in three of Beza's copies, but is in most Greek copies, and in Munster's Hebrew Gospel, and seems to be necessary.

Watch therefore; for ye know neither the day nor the hour wherein the Son of man cometh--This, the moral or practical lesson of the whole parable, needs no comment.

Watch therefore, for ye know neither the day nor the hour, etc. The whole parable is an illustration of this solemn admonition.
APPLICATION.--The Bridegroom is the Son of man; the time of the marriage is the coming to judgment; the tarrying is the long and unknown period between his ascension and his return; the virgins represent the waiting church; the wise virgins represent those church members who are always ready and whose lights are shining; the oil in their vessels is the means by which their light is supplied; the foolish virgins are church members who have become cold and lifeless; the midnight cry is the summons of death, or the trump of judgment; the cry for oil is death-bed repentance, or an attempt at preparation in the face of judgment; the shut door is a declaration that such repentance is too late to be of avail; the great lesson is to be always in a state of readiness.

Watch therefore - He that watches has not only a burning lamp, but likewise oil in his vessel. And even when he sleepeth, his heart waketh. He is quiet; but not secure.
