Isaiah 40:6-8

The voice said, “Cry out!” And he said, “What shall I cry?” “All flesh is grass, And all its loveliness is like the flower of the field. The grass withers, the flower fades, Because the breath of the Lord blows upon it; Surely the people are grass. The grass withers, the flower fades, But the word of our God stands forever.” — NKJV
