17 How frequently is the light of the evil-doers put out, or does trouble come on them? how frequently does his wrath take them with cords? 18 How frequently are they as dry stems before the wind, or as grass taken away by the storm-wind? 19 You say, God keeps punishment stored up for his children. Let him send it on the man himself, so that he may have the punishment of it! 20 Let his eyes see his trouble, and let him be full of the wrath of the Ruler of all! 21 For what interest has he in his house after him, when the number of his months is ended?
Matthew Henry's Commentary on Job 21:17-21
Commentary on Job 21:17-26
(Read Job 21:17-26)
Job had described the prosperity of wicked people; in these verses he opposes this to what his friends had maintained about their certain ruin in this life. He reconciles this to the holiness and justice of God. Even while they prosper thus, they are light and worthless, of no account with God, or with wise men. In the height of their pomp and power, there is but a step between them and ruin. Job refers the difference Providence makes between one wicked man and another, into the wisdom of God. He is Judge of all the earth, and he will do right. So vast is the disproportion between time and eternity, that if hell be the lot of every sinner at last, it makes little difference if one goes singing thither, and another sighing. If one wicked man die in a palace, and another in a dungeon, the worm that dies not, and the fire that is not quenched, will be the same to them. Thus differences in this world are not worth perplexing ourselves about.
