6The voice of one saying, Cry. One said, What shall I cry? All flesh is grass, and all the glory of it is as the flower of the field. 7The grass withers, the flower fades, because the breath of Yahweh blows on it; surely the people is grass. 8The grass withers, the flower fades; but the word of our God shall stand forever.
