1Be comforted, be comforted, my people, saith your God.

2Speak ye to the heart of Jerusalem, and call to her: for her evil is come to an end, her iniquity is forgiven: she hath received of the hand of the Lord double for all her sins.

3The voice of one crying in the desert: Prepare ye the way of the Lord, make straight in the wilderness the paths of our God.

4Every valley shall be exalted, and every mountain and hill shall be made low, and the crooked shall become straight, and the rough ways plain.

5And the glory of the Lord shall be revealed, and all flesh together shall see, that the mouth of the Lord hath spoken.

6The voice of one, saying: Cry. And I said: What shall I cry? All flesh is grass, and all the glory thereof as the flower of the field.

7The grass is withered, and the flower is fallen, because the spirit of the Lord hath blown upon it. Indeed the people is grass:

8The grass is withered, and the flower is fallen: but the word of our Lord endureth for ever.

9Get thee up upon a high mountain, thou that bringest good tidings to Sion: lift up thy voice with strength, thou that bringest good tidings to Jerusalem: lift it up, fear not. Say to the cities of Juda: Behold your God:

10Behold the Lord God shall come with strength, and his arm shall rule: Behold his reward is with him and his work is before him.

11He shall feed his flock like a shepherd: he shall gather together the lambs with his arm, and shall take them up in his bosom, and he himself shall carry them that are with young.

12Who hath measured the waters in the hollow of his hand, and weighed the heavens with his palm? who hath poised with three fingers the bulk of the earth, and weighed the mountains in scales, and the hills in a balance?

13Who hath forwarded the spirit of the Lord? or who hath been his counsellor, and hath taught him?

14With whom hath he consulted, and who hath instructed him, and taught him the path of justice, and taught him knowledge, and shewed him the way of understanding?

15Behold the Gentiles are as a drop of a bucket, and are counted as the smallest grain of a balance: behold the islands are as a little dust.

16And Libanus shall not be enough to burn, nor the beasts thereof sufficient for a burnt offering.

17All nations are before him as if they had no being at all, and are counted to him as nothing, and vanity.

18To whom then have you likened God? or what image will you make for him?

19Hath the workman cast a graven statue? or hath the goldsmith formed it with gold, or the silversmith with plates of silver?

20He hath chosen strong wood, and that will not rot: the skilful workman seeketh how he may set up an idol that may not be moved.

21Do you not know? hath it not been heard? hath it not been told you from the beginning? have you not understood the foundations of the earth?

22It is he that sitteth upon the globe of the earth, and the inhabitants thereof are as locusts: he that stretcheth out the heavens as nothing, and spreadeth them out as a tent to dwell in.

23He that bringeth the searchers of secrets to nothing, that hath made the judges of the earth as vanity.

24And surely their stock was neither planted, nor sown, nor rooted in the earth: suddenly he hath blown upon them, and they are withered, and a whirlwind shall take them away as stubble.

25And to whom have ye likened me, or made me equal, saith the Holy One?

26Lift up your eyes on high, and see who hath created these things: who bringeth out their host by number, and calleth them all by their names: by the greatness of his might, and strength, and power, not one of them was missing.

27Why sayest thou, O Jacob, and speakest, O Israel: My way is hid from the Lord, and my judgment is passed over from my God?

28Knowest thou not, or hast thou not heard? the Lord is the everlasting God, who hath created the ends of the earth: he shall not faint, nor labour, neither is there any searching out of his wisdom.

29It is he that giveth strength to the weary, and increaseth force and might to them that are not.

30You shall faint, and labour, and young men shall fall by infirmity.

31But they that hope in the Lord shall renew their strength, they shall take wings as eagles, they shall run and not be weary, they shall walk and not faint.

Catholic Commentary

In this 31-verse narrative, the sacred author records events that advance the story of judgment, comfort, and messianic hope. A pivotal line is verse 2: "Speak ye to the heart of Jerusalem, and call to her: for her evil is come to an end, her iniquity is forgiven: she hath received of the hand of the Lord double…" The passage repeatedly touches on worship and praise.

The Church teaches that every passage of Scripture must be read in light of Christ and the Magisterium (CIC 1700). Here, Isaiah's prophecies are fulfilled in Christ, especially the Suffering Servant (CIC 601). The spiritual sense invites believers to recognize worship and praise as part of God's pedagogy of salvation.

Applied to the life of faith, the passage supports the Church's conviction that God's salvation reaches to the ends of the earth. Whether read privately or heard in the liturgy, Isaiah 40 calls for a response of faith, repentance, and charity.

Reflection for Today

In Isaiah Chapter 40, the Church invites us to listen attentively to God's Word within the broader narrative of judgment, comfort, and messianic hope.

The Second Vatican Council reminded the faithful that Scripture should permeate Catholic spirituality (Dei Verbum, 21-26). Isaiah Chapter 40 supports that call by drawing attention to trust in providence amid uncertainty within the wider message that God's salvation reaches to the ends of the earth.

As you continue through Isaiah, carry this chapter's lesson into your family, parish, and work. Catholic faith is always ecclesial—God speaks to us as members of Christ's Body, not as isolated individuals.
