Isaías 40

28 Whether thou knowest not, either heardest thou not? God, everlasting Lord, that made of nought the ends of [the] earth, shall not fail, neither shall travail, neither ensearching of his wisdom is.

29 That giveth strength to the weary, and strength to them that be not, and multiplieth stalworth[y] ness.

30 Young men shall fail, and shall travail, and young men shall fall down in their sickness.

31 But they that hope in the Lord, shall change strength, they shall take feathers as eagles; they shall run, and shall not travail; they shall go, and shall not fail.
