“As for man, his days are as grass: as a flower of the field, so he flourisheth.”
King James Version (KJV)
Psalms 103:15 Context
12As far as the east is from the west, so far hath he removed our transgressions from us. 13Like as a father pitieth his children, so the LORD pitieth them that fear him. 14For he knoweth our frame; he remembereth that we are dust. 15As for man, his days are as grass: as a flower of the field, so he flourisheth. 16For the wind passeth over it, and it is gone; and the place thereof shall know it no more. 17But the mercy of the LORD is from everlasting to everlasting upon them that fear him, and his righteousness unto children's children; 18To such as keep his covenant, and to those that remember his commandments to do them.
Matthew Henry Commentary - Psalms 103:15-18
15-18 How short is man's life, and uncertain! The flower of the garden is commonly more choice, and will last the longer, for being sheltered by the garden-wall, and the gardener's care; but the flower of the field, to which life is here compared, is not only withering in itself, but exposed to the cold blasts, and liable to be cropt and trod on by the beasts of the field. Such is man. God considers this, and pities him; let him consider it himself. God's mercy is better than life, for it will outlive it. His righteousness, the truth of his promise, shall be unto children's children, who tread in the footsteps of their forefathers' piety. Then shall mercy be preserved to them.
