But know this,.... Or you do know this: this may be illustrated by supposing a case well known to men, and in which common prudence would direct a man how to behave:

that if the good man of the house, or householder, or master of the family,

had known in what watch the thief would come; whether at the first, second, third, or fourth watch; for the night was divided into four watches; had he any previous notice given by any of the associates of the thief, or by those that had overheard, or by any means had got intelligence of his design and measures, and the time of his pursuing them,

he would have watched; in every watch either in person, or by employing others, or both:

and would not have suffered his house to be broken up: or "dug through"; see Job 24:16 concerning which, there is a law in Exo 22:2 and is explained by the Jewish canonists thus:

"He that comes in by digging, whether by day or by night, there is no blood for him (i.e. to be shed for him, if he is killed); but if the master of the house, or any other man kill him, they are free; and every man has power to kill him, whether on a weekday, or on a sabbath day; and with whatsoever death he can put him to, as it is said, there is no blood for him, Exo 22:2. And one that comes in, "by digging", or a thief that is found in the midst of a man's roof, or in his court, or within his hedge, whether in the day or in the night, (may be killed;) and wherefore is it called digging? because it is the way of most thieves to come in by digging in the night (x).

Wherefore no doubt since the master of the house had such a law on his side, he would never suffer, if possible, his house to be entered by digging, when he had, especially, any previous notice of it. Now the application of this case, or parabolical way of speaking, is to the coming of Christ, and the watchfulness of every good man who has notice of it, that he may not be surprised with it, but be in a readiness to receive him. The coming of the son of man, is here represented by the coming of the thief in the night: but when he is compared to a thief, this is not to be understood in a bad sense, in which Satan is called one, who comes to kill and to destroy the souls of men; and likewise heretics and false teachers, and everyone that climbs up, and gets into the church of God in a wrong way; but this only respects the manner of Christ's coming, which is like that of a thief, secretly, suddenly, and at unawares. The "good man of the house", or householder, is every Christian, or believer in Christ, who has a house to look after, his own soul, the spiritual affairs and everlasting salvation of it, things of moment and concern unto him: and as the Christians, before the destruction of Jerusalem, had notices of Christ's coming in that way, by our Lord's predictions, by the hints the apostles gave, to refresh their memories with them, and by the signs of the times and voices that were heard; so the saints have of Christ's coming to judgment: wherefore as it became the one, so it does the other, to watch, to be upon their guard, to be in a readiness, to have their loins girt about, and their lights burning, and they like men that wait for their Lord; that so when he comes, their houses may not be broken up, may not be surprised, and the several powers and faculties of their souls may not be thrown into disorder and confusion; wherefore it follows,
