Commentary on Isaiah 40:4

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: Every valley shall be exalted - That is, every valley, or low piece of ground, shall be filled up so as to make a level highway, as was done in order to facilitate the march of armies. This verse is evidently designed to explain what is intended in Isaiah 40:3 , by preparing the way for Yahweh. Applied to the return of the Jews from Babylon, it means simply that the impassable valleys were to be filled up so as to make a level road for their journey.
