Isaiah 40:4-6

Amplified Bible

⁴
“Every valley shall be raised,
And every mountain and hill be made low;
And let the rough ground become a plain,
And the rugged places a broad valley.
⁵
“And the glory and majesty and splendor of the Lord will be revealed,
And all humanity shall see it together;
For the mouth of the Lord has spoken it.”^(A)
⁶
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.
