Matthew Poole and continuators on Luke 21:36

36 Watch ye therefore, and pray always that you may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.

I take the thirty fourth Verse to be a good Exposition of the Term Watch, v. 36. Avoid Sin, industriously in a prospect of my coming to Judgment: for Sin is compared to Sleep▪ Rom. 13.11. and Eph. 5.14. and as he that Watcheth doth not only Wake, but setteth himself designedly to forbear Sleep, in order to some end; so he who keepeth the Spiritual Watch, must set himself designedly to avoid Sin, upon a prospect of Christ's coming, and the incertainty of it. Particularly he cautioneth his Disciples against Luxury, and Wordlymindedness. The first he expresseth under the notions of Gluttony and Drunkenness, which are two Eminent Species of it. The latter, under the notion of the cares of this Life, not necessary and provident Cares, but Superfluous, and distracting Cares. These things he presseth them to avoid, lest they should be surprized by Christ's coming, as he tells them the most of the World would be. He further Exhorteth them to pray always, the Sense of which Precept we shewed largely in our Notes on Ch. 18.1. He further presseth both these Duties in those Words. That you may be accounted worthy to escape all these things that shall come to pass, but those that should come to pass at, or before the Destruction of Ierusalem, or afterward, and stand before the Son of Man, that is, in the last Judgment, for, The ungodly shall not stand in the Iudgment: nor Sinners in the Congergation of the Righteous, Psal. 1.6.
