1 “Comfort, comfort my people,” says your God.

2 “Speak comfortably to Jerusalem; and call out to her that her warfare is accomplished, that her iniquity is pardoned, that she has received of Yahweh’s hand double for all her sins.”

3 The voice of one who calls out, “Prepare the way of Yahweh in the wilderness! Make a level highway in the desert for our God.

4 Every valley shall be exalted, and every mountain and hill shall be made low. The uneven shall be made level, and the rough places a plain.

5 Yahweh’s glory shall be revealed, and all flesh shall see it together; for the mouth of Yahweh has spoken it.”

6 The voice of one saying, “Cry!” One said, “What shall I cry?” “All flesh is like grass, and all its glory is like the flower of the field.

7 The grass withers, the flower fades, because Yahweh’s breath blows on it. Surely the people are like grass.

8 The grass withers, the flower fades; but the word of our God stands forever.”

9 You who tell good news to Zion, go up on a high mountain. You who tell good news to Jerusalem, lift up your voice with strength! Lift it up! Don’t be afraid! Say to the cities of Judah, “Behold, your God!”

10 Behold, the Lord Yahweh will come as a mighty one, and his arm will rule for him. Behold, his reward is with him, and his recompense before him.

11 He will feed his flock like a shepherd. He will gather the lambs in his arm, and carry them in his bosom. He will gently lead those who have their young.

4 John came baptizing in the wilderness and preaching the baptism of repentance for forgiveness of sins.

5 All the country of Judea and all those of Jerusalem went out to him. They were baptized by him in the Jordan river, confessing their sins.

6 John was clothed with camel’s hair and a leather belt around his waist. He ate locusts and wild honey.

7 He preached, saying, “After me comes he who is mightier than I, the thong of whose sandals I am not worthy to stoop down and loosen.

8 I baptized you in water, but he will baptize you in the Holy Spirit.”

Original context

Isaiah 40 announces comfort for Jerusalem and a prepared way through the wilderness. The surrounding language concerns God's coming, the end of suffering and care for the people. The USCCB notes connect the image with the return of exiles from Babylon.

How the New Testament uses it

The Gospels apply the wilderness voice to John the Baptist preparing for Jesus. Mark's opening scriptural introduction combines material, so its wording should not all be attributed to Isaiah 40 alone. Luke quotes a longer portion of the Isaiah passage.

The Christian understanding

John's ministry is understood as preparation for God's saving action in Jesus.

Other readings and questions

The earlier text can be read as consolation and restoration for its own audience. The Gospel application can then be studied as a later theological reuse of a restoration promise.

What the connection can establish

The quotation establishes how the evangelists frame John and Jesus. Its historical and theological force depends on further judgments about the earlier promise, the ministry described and the connection between them.
