Every valley shall be exalted - That is, every valley, or low piece of ground, shall be filled up so as to make a level highway, as was done in order to facilitate the march of armies. This verse is evidently designed to explain what is intended in Isaiah 40:3, by preparing the way for Yahweh. Applied to the return of the Jews from Babylon, it means simply that the impassable valleys were to be filled up so as to make a level road for their journey. If applied to the work of John, the forerunner of the Messiah, it means that the nation was to be called on to put itself in a state of preparation for his coming, and for the success of his labors among them. Vitringa, and others, have endeavored to specify what particular moral qualities in the nation are meant by the 'valley,' by the 'mountain and hill,' and by the 'crooked' and 'rough places.' But the illustrations are such as cannot be demonstrated to be referred to by the prophet. The general sense is plain. The language, as we have seen, is taken from the march of a monarch at the head of his army. The general idea is, that all obstructions were to be removed, so that the march would be without embarrassment. As applicable to the work of John also, the language means in general, that whatever there was in the opinions, habits, conduct, in the pride, self-confidence, and irreligion of the nation that would prevent his cordial reception, was to be removed.

Every mountain and hill - They shall be dug down so as to make the journey easy. All obstructions were to be removed.

And the crooked - The word used here, (עקב ‛âqob) is usually rendered 'crooked;' but perhaps not by any good authority. The verb עקב ‛âqab usually denotes to be behind; to come from behind; or, as Gesenius supposes, to be elevated like a mound, arched like a hill or tumulus, and is hence applied to the heel from the figure (see Genesis 25:26; Hosea 12:4). According to this, the word would denote properly a hill, mound, or acclivity, which would put back those who attempted to ascend.

Shall be made straight - Margin, 'A straight place.' The Hebrew word (מישׁור mı̂yshôr) denotes properly "evenness," a level region, a plain. The hilly places would be reduced to a level.

And the rough places - Those which are hard, bound up, stony, difficult to pass. Such as abounded with rocks and precipices, and which presented obstructions to a journey. Such places abounded in the region lying between Palestine and Babylon.

Plain - Margin, 'A plain place.' A smooth, level plain.

Crooked - The word עקב akob is very generally rendered crooked: but this sense of the word seems not to be supported by any good authority. Ludolphus, Comment. ad Hist. Aethiop. p. 206, says "that in the Ethiopia language it signifies clivus, locus editus:" and so the Syriac Version renders it in this place, ערמא arama: Hebrew, ערמה aramah, tumulus, acervus. Thus the parallelism would be more perfect:" the hilly country shall be made level, and the precipices a smooth plain."

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.

The summons proceeds in a commanding tone. "Let every valley be exalted, and every mountain and hill made low; and let the rugged be made a plain, and the ledges of rocks a valley." והיה, which takes its tone from the two jussive verbs, is also itself equivalent to ויהי. Instead of גּיא (from גּיא), the pointing in Zechariah 14:4, we have here (according to Kimchi) the vowel-pointing גּיא; at the same time, the editions of Brescia, Pesaro, Venice 1678, have גּיא (with tzere), and this is also the reading of a codex of Luzzatto without Masoretic notes. The command, according to its spiritual interpretation, points to the encouragement of those that are cast down, the humiliation of the self-righteous and self-secure, the changing of dishonesty into simplicity, and of unapproachable haughtiness into submission (for ‛âqōbh, hilly, rugged,

(Note: In this ethical sense Essex applied the word to Queen Elizabeth. See Hefele, Ximenes, p. 90 (ed. 2).)

compare Jeremiah 17:9 together with Habakkuk 2:4). In general, the meaning is that Israel is to take care, that the God who is coming to deliver it shall find it in such an inward and outwards state as befits His exaltation and His purpose.

Every valley shall be exalted, and every {g} mountain and hill shall be made low: and the crooked shall be made straight, and the rough places plain:

(g) Whatever may prevent or hinder this deliverance will be removed.

straight: or, a straight place

plain: or, a plain place

4. Eastern monarchs send heralds before them in a journey to clear away obstacles, make causeways over valleys, and level hills. So John's duty was to bring back the people to obedience to the law and to remove all self-confidence, pride in national privileges, hypocrisy, and irreligion, so that they should be ready for His coming (Mal 4:6; Lu 1:17).

crooked-declivities.

40:1-11 All human life is a warfare; the Christian life is the most so; but the struggle will not last always. Troubles are removed in love, when sin is pardoned. In the great atonement of the death of Christ, the mercy of God is exercised to the glory of his justice. In Christ, and his sufferings, true penitents receive of the Lord's hand double for all their sins; for the satisfaction Christ made by his death was of infinite value. The prophet had some reference to the return of the Jews from Babylon. But this is a small event, compared with that pointed out by the Holy Ghost in the New Testament, when John the Baptist proclaimed the approach of Christ. When eastern princes marched through desert countries, ways were prepared for them, and hinderances removed. And may the Lord prepare our hearts by the teaching of his word and the convictions of his Spirit, that high and proud thoughts may be brought down, good desires planted, crooked and rugged tempers made straight and softened, and every hinderance removed, that we may be ready for his will on earth, and prepared for his heavenly kingdom. What are all that belongs to fallen man, or all that he does, but as the grass and the flower thereof! And what will all the titles and possessions of a dying sinner avail, when they leave him under condemnation! The word of the Lord can do that for us, which all flesh cannot. The glad tidings of the coming of Christ were to be sent forth to the ends of the earth. Satan is the strong man armed; but our Lord Jesus is stronger; and he shall proceed, and do all that he purposes. Christ is the good Shepherd; he shows tender care for young converts, weak believers, and those of a sorrowful spirit. By his word he requires no more service, and by his providence he inflicts no more trouble, than he will strengthen them for. May we know our Shepherd's voice, and follow him, proving ourselves his sheep.
