Isaiah 40:6 in the King James Version
The voice said, Cry. And he said, What shall I cry? All flesh is grass, and all the goodliness thereof is as the flower of the field:
Context
5 The LORD’s glory shall be revealed, and all flesh shall see it together; for the mouth of the LORD has spoken it.”
6 The voice of one saying, “Cry out!” One said, “What shall I cry?” “All flesh is like grass, and all its glory is like the flower of the field.
7 The grass withers, the flower fades, because the LORD’s breath blows on it. Surely the people are like grass.
