Isaiah 40:6-7

A voice says, “Call out [prophesy].” Then he answered, “What shall I call out?” [The voice answered:] All humanity is [as frail as] grass, and all that makes it attractive [its charm, its loveliness] is [momentary] like the flower of the field. The grass withers, the flower fades, When the breath of the LORD blows upon it; Most certainly [all] the people are [like] grass.
