Isaiah 40:4

4 Every valley shall be raised up, and every mountain and hill shall be brought low; and the crooked shall be made straight, and the rough places a plain.

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 to the heart of Jerusalem, and cry unto her, that her time of suffering is accomplished, that her iniquity is pardoned; for she hath received of Jehovah's hand double for all her sins.

3 The voice of one crying in the wilderness: Prepare ye the way of Jehovah, make straight in the desert a highway for our God!

4 Every valley shall be raised up, and every mountain and hill shall be brought low; and the crooked shall be made straight, and the rough places a plain.

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

6 A voice saith, Cry. And he saith, What shall I cry? -- All flesh is grass, and all the comeliness thereof as the flower of the field.
