Isaiah 40:4

4 Every valley should be raised up, and every mountain and hill should be made flat. The rough ground should be made level, and the rugged ground should be made smooth.

Isaiah 40:4 Meaning and Commentary

Isaiah 40:4

Every valley shall be exalted, and every mountain and hill
shall be made low
Which is not to be understood literally, but, as Kimchi says, parabolically and mystically: the meaning is, that in consequence of John's ministry, and our Lord's coming, such who were depressed and bowed down with the guilt of sin, and were low and humble in their own eyes, should be raised up and comforted; and that such who were elated with themselves, and their own righteousness, should be humbled; their pride and haughtiness should be brought down, and they treated with neglect and contempt, while great notice was taken of lowly minded ones; see ( Luke 14:11 ) and ( Luke 18:14 ) : and the crooked shall be straight and the rough places plain;
what before was dark and intricate in prophecy should now become clear; and such doctrines as were not so well understood should now become plain and easy.

Isaiah 40:4 In-Context

2 Speak kindly to the people of Jerusalem and tell them that their time of service is finished, that they have paid for their sins, that the Lord has punished Jerusalem twice for every sin they did."

3 This is the voice of one who calls out: "Prepare in the desert the way for the Lord. Make a straight road in the dry lands for our God.

4 Every valley should be raised up, and every mountain and hill should be made flat. The rough ground should be made level, and the rugged ground should be made smooth.

5 Then the glory of the Lord will be shown, and all people together will see it. The Lord himself said these things."

6 A voice says, "Cry out!" Then I said, "What shall I cry out?" "Say all people are like the grass, and all their glory is like the flowers of the field.
