Verse 6. - In the morning it flourisheth, and groweth up; in the evening it is cut down, and withered (comp. Psalm 102:4, 11 103:15; Isaiah 40:7; James 1:10, 11).

90:1-6 It is supposed that this psalm refers to the sentence passed on Israel in the wilderness, Nu 14. The favour and protection of God are the only sure rest and comfort of the soul in this evil world. Christ Jesus is the refuge and dwelling-place to which we may repair. We are dying creatures, all our comforts in the world are dying comforts, but God is an ever-living God, and believers find him so. When God, by sickness, or other afflictions, turns men to destruction, he thereby calls men to return unto him to repent of their sins, and live a new life. A thousand years are nothing to God's eternity: between a minute and a million of years there is some proportion; between time and eternity there is none. All the events of a thousand years, whether past or to come, are more present to the Eternal Mind, than what was done in the last hour is to us. And in the resurrection, the body and soul shall both return and be united again. Time passes unobserved by us, as with men asleep; and when it is past, it is as nothing. It is a short and quickly-passing life, as the waters of a flood. Man does but flourish as the grass, which, when the winter of old age comes, will wither; but he may be mown down by disease or disaster.In the morning it flourisheth and groweth up,.... That is, the grass, through the dew that lay all night on it, and by the clear shining of the sun after rain, when it appears in great beauty and verdure; so man in the morning of his youth looks gay and beautiful, grows in the stature and strength of his body, and in the endowments of his mind; and it may be also in riches and wealth; it is well if he grows in grace, and in the knowledge of Christ:

in the evening it is cut down, and withereth; the Targum adds, "through heat"; but it cannot be by the heat of the sun, when it is cut down at evening; but it withers in course, being cut down. This respects the latter part of life, the evening of old age; and the whole expresses the shortness of life, which is compared to grass, that now is in all its beauty and glory, and tomorrow is cast into the oven, Matthew 6:30. This metaphor of grass, to set forth the frailty of man, and his short continuance, is frequently used; see Psalm 37:2, 1 Peter 1:24. It may be observed, that man's life is represented but as one day, consisting of a morning and an evening, which signifies the bloom and decline of life.
