29He gives strength to the weary,
         And to him who lacks might He increases power.

30Though youths grow weary and tired,
         And vigorous young men stumble badly,

31Yet those who wait for the LORD
         Will gain new strength;
         They will mount up with wings like eagles,
         They will run and not get tired,
         They will walk and not become weary.

NASB ©1995

World English Bible

Young's Literal Translation
He is giving power to the weary, And to those not strong He increaseth might.April 18. "They Shall Mount up with Wings" (Isa. Xl. 31).
"They shall mount up with wings" (Isa. xl. 31). "They shall mount up with wings as eagles," is God's preliminary; for the next promise is, "They shall run and not be weary, and they shall walk and not faint." Hours of holy exultation are necessary for hours of patient plodding, waiting and working. Nature has its springs, and so has grace. Let us rejoice in the Lord evermore, and again we say, rejoice. And let us take Him to be our continual joy, whose heart is a fountain of blessedness, and who …

'Have Ye Not? Hast Thou Not?'
'Have ye not known, have ye not heard? hath it not been told yon from the beginning? have ye not understood from the foundations of the earth?... Hast thou not known? hast thou not heard?'--ISAIAH xl. 21 and 28. The recurrence of the same form of interrogation in these two verses is remarkable. In the first case the plural is used, in the second the singular, and we may reasonably conclude that as Israel is addressed in the latter, the nations outside the sphere illumined by Revelation are appealed …

Unfailing Stabs and Fainting Men
'...For that He is strong in power; not one faileth.... He giveth power to the faint; and to them that have no might He increaseth strength.'-- ISAIAH xl. 26 and 29. These two verses set forth two widely different operations of the divine power as exercised in two sadly different fields, the starry heavens and this weary world. They are interlocked, as it were, by the recurrence in the latter of the emphatic words of the former. The one verse says, 'He is strong in power'; the other, 'He giveth …

O Thou that Bringest Good Tidings
'O Zion, that bringest good tidings, get thee up into the high mountain: O Jerusalem, that bringest good tidings, lift up thy voice with strength; lift it up, be not afraid; say unto the cities of Judah, Behold your God!'--ISAIAH xl. 9. There is something very grand in these august and mysterious voices which call one to another in the opening verses of this chapter. First, the purged ear of the prophet hears the divine command to him and to his brethren--Comfort Jerusalem with the message of the …

The Shepherd and the Fold
... Thou hast guided them in Thy strength unto Thy holy habitation.' EXODUS XV. 13. What a grand triumphal ode! The picture of Moses and the children of Israel singing, and Miriam and the women answering: a gush of national pride and of worship! We belong to a better time, but still we can feel its grandeur. The deliverance has made the singer look forward to the end, and his confidence in the issue is confirmed. I. The guiding God: or the picture of the leading. The original is 'lead gently.' Cf. …

The Secret of Immortal Youth
'Even the youths shall faint and be weary, and the young men shall utterly fall. But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run and not be weary; and they shall walk and not faint.'--ISAIAH xl. 30, 31. I remember a sunset at sea, where the bosom of each wavelet that fronted the west was aglow with fiery gold, and the back of each turned eastward was cold green; so that, looking on the one hand all was glory, and on the other …

Salvation Published from the Mountains
O Zion, that bringest good tidings, get thee up into the high mountain; O Jerusalem, that bringest good tidings, lift up thy voice with strength; lift it up, be not afraid: say unto the cities of Judah, Behold your God! I t would be improper to propose an alteration, though a slight one, in the reading of a text, without bearing my testimony to the great value of our English version, which I believe, in point of simplicity, strength, and fidelity, is not likely to be excelled by a new translation …

The Consolation
Comfort ye, comfort ye my people, saith your God. Speak ye comfortably to Jerusalem, and cry unto her, that her warfare is accomplished, that her iniquity is pardoned: for she hath received at the LORD 's hand double for all her sins. T he particulars of the great "mystery of godliness," as enumerated by the Apostle Paul, constitute the grand and inexhaustible theme of the Gospel ministry, "God manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on …

The Harbinger
The voice of him that crieth in the wilderness, Prepare ye the way of the LORD , make straight in the desert a high-way for our God. Every valley shall be exalted, and every mountain and hill shall be made low, and the crooked shall be made straight, and the rough places plain. And the glory of the LORD shall be revealed, and all flesh shall see it together, for the mouth of the LORD hath spoken it. T he general style of the prophecies is poetical. The inimitable simplicity which characterizes every …

The Withering Work of the Spirit
THE passage in Isaiah which I have just read in your hearing may be used as a very eloquent description of our mortality, and if a sermon should be preached from it upon the frailty of human nature, the brevity of life, and the certainty of death, no one could dispute the appropriateness of the text. Yet I venture to question whether such a discourse would strike the central teaching of the prophet. Something more than the decay of our material flesh is intended here; the carnal mind, the flesh in …

This Sermon was Originally Printed
"Comfort ye, comfort ye my people, saith your God."--Isaiah 40:1. WHAT A SWEET TITLE: "My people!" What a cheering revelation: "Your God!" How much of meaning is couched in those two words, "My people!" Here is speciality. The whole world is God's; the heaven, even the heaven of heavens are the Lord's and he reigneth among the children of men. But he saith of a certain number, "My people." Of those whom he hath chosen, whom he hath purchased to himself, he saith what he saith not of others. While …
