Isaiah 40:3-8

A voice is crying out: “Clear the LORD’s way in the desert! Make a level highway in the wilderness for our God! Every valley will be raised up, and every mountain and hill will be flattened. Uneven ground will become level, and rough terrain a valley plain. The LORD’s glory will appear, and all humanity will see it together; the LORD’s mouth has commanded it.” A voice was saying: “Call out!” And another said, “What should I call out?” All flesh is grass; all its loyalty is like the flowers of the field. The grass dries up and the flower withers when the LORD’s breath blows on it. Surely the people are grass. The grass dries up; the flower withers, but our God’s word will exist forever.
