Isaiah 40:28

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.

Isaiah 40:30

30 Even the youths shall faint and be weary, and the young men shall utterly fall:

Isaiah 40:31

31 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 44:12

12 The smith with the tongs both worketh in the coals, and fashioneth it with hammers, and worketh it with the strength of his arms: yea, he is hungry, and his strength faileth: he drinketh no water, and is faint.
