Context — Here Is Your God!

26Lift up your eyes on high: Who created all these? He leads forth the starry host by number; He calls each one by name. Because of His great power and mighty strength, not one of them is missing. 27Why do you say, O Jacob, and why do you assert, O Israel, “My way is hidden from the LORD, and my claim is ignored by my God”?

28Do you not know? Have you not heard? The LORD is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary; His understanding is beyond searching out.

29He gives power to the faint and increases the strength of the weak. 30Even youths grow tired and weary, and young men stumble and fall.

Jamieson-Fausset-Brown on Isaiah 40:28

Hast thou not known? hast thou not heard that the everlasting God the LORD the Creator of the ends of Hast thou not known?

Matthew Poole's Commentary on Isaiah 40:28

Of the ends of the earth; of all the earth, and the inhabitants thereof, from one end to another. He seems to mention the ends or utmost bounds, because they might seem to be more out of the reach and care of God’ s providence, as being most remote from Jerusalem, the only place of God’ s solemn and public worship in the world, and being then thought to be uninhabited. The argument is clear and strong: God, who made all, even the most desolate and barbarous parts of the earth, and consequently takes care of them, will not neglect his own land and people. Fainteth not, neither is weary; he is not by age or hard labour become weak and unable to help his people, as men are apt to be. There is no searching of his understanding; his counsels, by which he governeth all the world, and in a most particular manner thine affairs, are far above the reach of thy understanding; and therefore thou dost ignorantly and foolishly in passing so rash a censure upon the ways and works of the infinitely wise God.

Trapp's Commentary on Isaiah 40:28

Isaiah 40:28 Hast thou not known? hast thou not heard, [that] the everlasting God, the LORD, the Creator of the ends of the earth, fainteth not, neither is weary? [there is] no searching of his understanding.Ver. 28. He fainteth not, nor is weary.] Or, He is neither tired nor toiled, viz., as earthly judges may be. And his own people, for thinking otherwise of him, are here taken up as tartly as those idolaters before, with, "Hast thou not known? hast thou not heard?" There is no searching of his understanding.] Submit to him therefore as to the only wise God. This the very heathens taught men to do, as Plutarch. De sera Num. Vindic.

Ellicott's Commentary on Isaiah 40:28

(28) Hast thou not known? . . .—The questions are parallel to those of Isa 40:21, but are addressed to the Israel of God, rather than, as those were, to mankind. The Creator of the ends of the earth.—The word emphasises the thought that the whole earth, from the Euphrates to the “islands” of the sea, is subject to the power of the Eternal. Fainteth not, neither is weary? . . .—Had Isaiah learnt to feel that even his own phrase as to men “wearying God” (Isaiah 7:13) was too boldly anthropomorphic, and might, therefore, be misleading? No searching of his understanding.—The words come, like so many others like it, from Job (Isaiah 5:9; Isaiah 9:10), and must have been in St. Paul’s mind as he wrote Romans 11:33.

Adam Clarke's Commentary on Isaiah 40:28

Verse 28. There is no searching of his understanding - "And that his understanding is unsearchable."] Twenty-four MSS., two editions, the Septuagint and Vulgate, read ואין veein, with the conjunction ו vau.

He fainteth not] a new sentence. there is no searching …] Therefore it must be for wise reasons that Deep in unfathomable mines Of never-failing skill He treasures up His bright designs, etc. 29 should be joined in one verse with the last two lines of Isa 40:28. Not only is Jehovah never weary, but He gives strength to them who are weary.

Barnes' Notes on Isaiah 40:28

Hast thou not known? - This is the language of the prophet reproving them for complaining of being forsaken and assuring them that God was faithful to his promises.

Whedon's Commentary on Isaiah 40:28

28. Hast thou not known — The words here go on with the same reassuring intent. After the first pair of questions of Isa 40:21, the affirmation is: This eternal, all-perfect God does not tire of the humble supplicant’s appeal.
