{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; Mt 24:29,25:13.

People's New Testament

16:15 Behold, I come as a thief. This is interposed in order to give a place for exhortation to be always ready. The Lamb comes when men do not see him.

Wesley's Notes

16:15 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.

Jamieson-Fausset-Brown Bible Commentary

15. 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-(Mt 24:43; 2Pe 3:10).

they-saints and angels.

shame-literally, "unseemliness" (Greek, "aschemosunee"): Greek, 1Co 13:5: a different word from the Greek in Re 3:18 (Greek, "aischunee").

Matthew Henry's Concise Commentary

16:12-16 This probably shows the destruction of the Turkish power, and of idolatry, and that a way will be made for the return of the Jews. Or, take it for Rome, as mystical Babylon, the name of Babylon being put for Rome, which was meant, but was not then to be directly named. When Rome is destroyed, her river and merchandise must suffer with her. And perhaps a way will be opened for the eastern nations to come into the church of Christ. The great dragon will collect all his forces, to make one desperate struggle before all be lost. God warns of this great trial, to engage his people to prepare for it. These will be times of great temptation; therefore Christ, by his apostle, calls on his professed servants to expect his sudden coming, and to watch that they might not be put to shame, as apostates or hypocrites. However Christians differ, as to their views of the times and seasons of events yet to be brought to pass, on this one point all are agreed, Jesus Christ, the Lord of glory, will suddenly come again to judge the world. To those living near to Christ, it is an object of joyful hope and expectation, and delay is not desired by them.
