Isaiah 40:4
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
Every valley shall be exalted, and every mountain and hill shall be made low: and the crooked shall be made straight (note: Or, a straight place), and the rough places plain (note: Or, a plain place):
Every valley shall be lifted up, and every mountain and hill made low; the uneven ground will become smooth, and the rugged land a plain (note: LXX Every valley shall be filled in, and every mountain and hill shall be brought low. All the crooked ways shall become straight, and the rough places plains. Cited in Luke 3:5).
