Isaiah 40:31 BBE

²⁹  He gives power to the feeble, increasing the strength of him who has no force.

³⁰  Even the young men will become feeble and tired, and the best of them will come to the end of his strength;

³¹  But those who are waiting for the Lord will have new strength; they will get wings like eagles: running, they will not be tired, and walking, they will have no weariness.
