Isaiah 40

28Did you not know? Have you not heard? The everlasting Elohim, יהוה, the Creator of the ends of the earth, neither faints nor is weary. His understanding is unsearchable.

29He gives power to the faint, and to those who have no might He increases strength.

30Even youths shall faint and be weary, and young men stumble and fall,

31but those who wait on יהוה renew their strength, they raise up the wing like eagles, they run and are not weary, they walk and do not faint.
