King James Version

What Does Isaiah 40:5 Mean?

“And the glory of the LORD shall be revealed, and all flesh shall see it together: for the mouth of the LORD hath spoken it.”

Context

The voice of him that crieth in the wilderness, Prepare ye the way of the LORD, make straight in the desert a highway for our God.

Every valley shall be exalted, and every mountain and hill shall be made low: and the crooked shall be made straight, and the rough places plain: straight: or, a straight place plain: or, a plain place

And the glory of the LORD shall be revealed, and all flesh shall see it together: for the mouth of the LORD hath spoken it.

The voice said, Cry. And he said, What shall I cry? All flesh is grass, and all the goodliness thereof is as the flower of the field:

The grass withereth, the flower fadeth: because the spirit of the LORD bloweth upon it: surely the people is grass.

Commentary

Ellicott’s Commentary for English Readers

(5) **The glory of the Lord shall be revealed.**—Did the prophet think of a vision of a glory-cloud, like the Shechinah which he had seen in the Temple? or had he risen to the thought of the glory of character and will, of holiness and love? (John 1:14.) **All flesh.**—The revelation is not for Israel only, but for mankind. So in Luke 3:6, the words are quoted from the LXX., “all flesh shall see the salvation of God.” The phrase meets us here for the first time, and occurs again in Isaiah 49:26; Isaiah 66:16; Isaiah 66:23-24, marking, so to speak, the growing catholicity of the prophet’s thoughts. (See Note on Isaiah 38:11.)
