От Луки 21:36

Watch ye therefore, and pray always - Perhaps we should connect ες παντι καιρῳ, continually, with αγρυπνειτε, watch, as it appears to be the most natural order. Indeed the word continually belongs equally to both watch and pray; and no man is safe, at any time, who does not attend to this advice as literally as possible. That shall come to pass - That is, the tribulations which are on their way to overwhelm and destroy the Jewish people. These are sufficiently stated in the preceding verses. To stand before the Son of man - To be acquitted, and to be condemned, are expressed, in Rom 14:4, by standing and falling. Those who were faithful to the grace they had received were not only not destroyed in the destruction of Jerusalem, but became heralds of the grace and mercy of God to the nations. Thus they were counted worthy to stand before the Son of man - to minister salvation in his name.

Watch . . . pray, &c.--the two great duties which in prospect of trial are constantly enjoined. These warnings, suggested by the need of preparedness for the tremendous calamities approaching, and the total wreck of the existing state of things, are the general improvement of the whole discourse, carrying the mind forward to Judgment and Vengeance of another kind and on a grander and more awful scale--not ecclesiastical or political but personal, not temporal but eternal--when all safety and blessedness will be found to lie in being able to "STAND BEFORE THE SON OF MAN" in the glory of His personal appearing.

And he looked up,.... As Christ sat over against the treasury, looking upon the ground, he lift up his eyes; for the treasury was not in an high place, or above Christ, who was right against it. The Syriac, Arabic, and Persic versions leave out this clause. And saw the rich men casting their gifts into the treasury; See Gill on Mar 12:41.

In this chapter we have, I. The notice Christ took, and the approbation he gave, of a poor widow that cast two mites into the treasury (Luk 21:1-4). II. A prediction of future events, in answer to his disciples' enquiries concerning them (Luk 21:5-7). 1. Of what should happen between that and the destruction of Jerusalem - false Christs arising, bloody wars and persecutions of Christ's followers (Luk 21:8-19). 2. Of that destruction itself (Luk 21:20-24). 3. Of the second coming of Jesus Christ to judge the world, under the type and figure of that (Luk 21:25-33). III. A practical application of this, by way of caution and counsel (Luk 21:34-36), and an account of Christ's preaching and the people's attendance on it (Luk 21:37, Luk 21:38).

21:36 To stand before means “to pass the test” and stand approved before Jesus Christ at his second coming.
