Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.

(Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walked naked, and they see his shame.)

(Behold, I come as a thief. Blessed is he that watches and keeps his garments, that he may not walk naked, and that they may not see his shame.)

lo, I do come as a thief; happy is he who is watching, and keeping his garments, that he may not walk naked, and they may see his unseemliness,',

Behold, I come as a thief. Blessed is he that watches, and keeps his garments, lest he walk naked, and they see his shame.

(See, I come as a thief. Happy is he who is watching and keeps his robes, so that he may not go unclothed, and his shame be seen.)

Look, I am coming like a thief. Blessed is he who watches, and keeps his clothes, so that he does not walk naked, and they see his shame.

"Behold, I arrive like a thief. Blessed is he who is vigilant and who preserves his vestment, lest he walk naked and they see his disgrace."

('I am coming like a thief! Happy will he be who is on the watch, and keeps his clothing at hand, so that he will not have to walk about unclothed and let men see his nakedness.')

Behold, I come as a thief - That is, suddenly and unexpectedly. See the Matthew 24:43 note; 1-Thessalonians 5:2 note. This is designed evidently to admonish people to watch, or to be in readiness for his coming, since, whenever it would occur, it would be at a time when people were not expecting him.
Blessed is he that watcheth - Compare Matthew 24:42-44. The meaning here is, that he who watches for these events, who marks the indications of their approach, and who is conscious of a preparation for them, is in a better and happier state of mind than he on whom they come suddenly and unexpectedly.
And keepeth his garments - The allusion here seems to be to one who, regardless of danger, or of the approach of an enemy, should lay aside his garments and lie down to sleep. Then the thief might come and take away his garments, leaving him naked. The essential idea, therefore, here, is the duty of vigilance. We are to be awake to duty and to danger; we are not to be found sleeping at our post; we are to be ready for death - ready for the coming of the Son of man.
Lest he walk naked - His raiment being carried away while he is asleep.
And they see his shame - Compare the notes on Revelation 3:18. The meaning here is, that, as Christians are clothed with the garments of righteousness, they should not lay them aside, so that their spiritual nakedness should be seen. They are to be always clothed with the robes of salvation; always ready for any event, however soon or suddenly it may come upon them.

Behold, I come as a thief - Here is a sudden but timely warning to put every man on his guard, when this sudden and generally unexpected tribulation should take place.
Keepeth his garments, lest he walk naked - Here is a plain allusion to the office of him who was called the prefect or overseer, of the mountain of the temple. His custom was to go his rounds during the watches of the night; and if he found any of the Levites sleeping on his watch, he had authority to beat him with a stick, and burn his vestments. See Middoth, fol. 34, 1, and Tamid. fol. 27, 2; 28, 1. Such a person being found on his return home naked, it was at once known that he had been found asleep at his post, had been beaten, and his clothes burnt; thus his shame was seen - he was reproached for his infidelity and irreligion.

(18) Behold, I come as a thief. Blessed [is] he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.
(18) A parenthesis for admonition, in which God warns his holy servants, who rest in the expectation of Christ, always to think of his coming, and to look to themselves, that they be not shamefully made naked and circumvented of these unclean spirits, and so they be miserable unprepared at the coming of the Lord; (Matthew 24:29, Matthew 25:13).

Behold I come as a thief,.... These are the words of Christ, inserted in a parenthesis in this account, before it is concluded, to acquaint his people with his near and sudden approach, and to give them a word of caution and exhortation in these times of difficulty; for he is the Lord God Almighty, who sent forth these angels to pour out their vials, and whose judgments are applauded as righteous, Revelation 16:1 and who so often in Revelation 22:7 says "I come quickly"; and which is to be understood not of his spiritual coming, which will be already at this time, but of his personal coming: and which will be "as a thief": as it is often expressed, 1-Thessalonians 5:2 not in the bad sense, to steal and kill, and to destroy, though Christ's coming will issue in the everlasting destruction of the wicked; but the phrase is designed to express the suddenness of his coming, and the surprise of it:
blessed is he that watcheth; against sin, the lusts of the flesh, and the cares of this life, lest they bring a sleepiness upon him, and so the day of the Lord come upon him at an unawares; and against Satan and his temptations, who goes about seeking whom he may devour; and against his emissaries and false teachers, who lie in wait to deceive; and blessed is he also who is wishing and waiting for the coming of Christ, and so, being ready, will enter with him into the marriage chamber, and partake of the supper of the Lamb:
and keepeth his garments: either his conversation garments, unspotted from the world, and whenever defiled washes them, and makes them white in the blood of the Lamb; and keeps them from being stripped of them, by those who would lead them into sinful ways; or that keeps and holds fast the robe of Christ's righteousness, and garments of his salvation, which are the righteousness of the saints, that fine linen clean and white, that white raiment which only can cover their nakedness, that the shame thereof does not appear, Revelation 19:8
lest he walk naked; (b), "naked of the commandments", or good works, according to the Jewish phrase; having lost, or dropped his conversation garments:
and they see his shame; or lest, being naked, he be exposed to shame and confusion, yea, to everlasting ruin and destruction; see Matthew 22:12 the allusion is to the burning of the garments of those priests who were found asleep when upon their watch in the temple: the account that is given is this (c);
"the man of the mountain of the house (the governor of the temple) goes round all the wards (every night) with burning torches before him; and in every ward where the person does not stand upon his feet, the man of the mountain of the house says to him, peace be to thee; if he finds he is asleep, he strikes him with his staff, and he has power to burn his clothes; and they say (in Jerusalem) what voice is that in the court? (it is answered) the voice of a Levite beaten, and his clothes burnt, because he slept in the time of his watch; R. Eliezer ben Jacob says, once they found my mother's brother asleep, and they burnt his clothes:''
now imagine with what shame the poor Levite so served must appear the next morning among his brethren, with his clothes burnt, and he naked; and with greater shame and confusions must he appear at the last day that is destitute of the righteousness of Christ.
(b) Yalkut Simeoni, par. 2. fol. 91. 3. (c) Misna Middot, c. 1. sect. 2. T. Bab. Tamid, fol. 27. 2. & 28. 1. Maimon. Beth Habbechira, c. 8. sect. 10. & Cele Hamikdash, c. 7. sect. 4.

The gathering of the world kings with the beast against the Lamb is the signal for Christ's coming; therefore He here gives the charge to be watching for His coming and clothed in the garments of justification and sanctification, so as to be accepted.
thief-- (Matthew 24:43; 2-Peter 3:10).
they--saints and angels.
shame--literally, "unseemliness" (Greek, "aschemosunee"): Greek, 1-Corinthians 13:5 : a different word from the Greek in Revelation 3:18 (Greek, "aischunee").

Behold, I come as a thief - Suddenly, unexpectedly. Observe the beautiful abruptness. I - Jesus Christ. Hear him. Happy is he that watcheth. - Looking continually for him that "cometh quickly." And keepeth on his garments - Which men use to put off when they sleep. Lest he walk naked, and they see his shame - Lest he lose the graces which he takes no care to keep, and others see his sin and punishment.
