Isaiah 40:6-8 NIV

[6] A voice says, “Cry out.” And I said, “What shall I cry?” “All people are like grass, and all their faithfulness is like the flowers of the field. [7] The grass withers and the flowers fall, because the breath of the LORD blows on them. Surely the people are grass. [8] The grass withers and the flowers fall, but the word of our God endures forever.”
