Psalm 103:15

As for man, his days are as grass
He himself is like the grass which springs out of the earth; continues on it for a time, and then drops into it; the continuance of the grass is very short, it flourishes in the morning, is cut down at evening, and withers; see ( Psalms 90:5 Psalms 90:6 ) . As a flower of the field, so he flourisheth; which denotes the goodliness of man, and describes him in his best estate, as possessed of health, riches, honour, and all the gifts and endowments of nature; and yet, with all these, is only like a field flower, exposed to every wind, liable to be cropped by every hand, and to be trampled upon by the beasts of the field; and therefore flourishes not long: so very precarious and uncertain is man in his most flourishing circumstances; see ( Isaiah 40:6-8 ) .
