Ісая 40:28

The groundlessness of such despondency is set before them in a double question. "Is it not known to thee, or hast thou not heard, an eternal God is Jehovah, Creator of the ends of the earth: He fainteth not, neither becomes weary; His understanding is unsearchable." Those who are so desponding ought to know, if not from their own experience, at least from information that had been handed down, that Jehovah, who created the earth from one end to the other, so that even Babylonian was not beyond the range of His vision or the domain of His power, was an eternal God, i.e., a God eternally the same and never varying, who still possessed and manifested the power which He had displayed in the creation. Israel had already passed through a long history, and Jehovah had presided over this, and ruled within it; and He had not so lost His power in consequence, as to have now left His people to themselves. He does not grow faint, as a man would do, who neglected to take the repeated nourishment requisite to sustain the energy of his vital power; nor does He become weary, like a man who has exhausted his capacity for work by over-exertion. And if He had not redeemed His people till then, His people were to know that His course was pure tebhūnâh or understanding, which was in the possession of infallible criteria for determining the right point of time at which to interpose with His aid.

40:28 heard . . . understood: Cp. 40:21. • the everlasting God, the Creator of all the earth: Creation reveals God’s power and wisdom. He is also the Creator of the age to come, a world of righteousness, justice, and peace (45:8; 48:6-7; 65:17-18). • He never grows weak or weary: God is not susceptible to human limitations.
