28 Have you not known? Have you not heard? Adonai is the eternal God, the Creator of the ends of the earth. He does not grow tired or weary. His understanding is unsearchable.
29 He gives strength to the weary, and to one without vigor He adds might.
30 Even youths grow tired and weary, and young men stumble and fall,
31 but they who wait for Adonai will renew their strength. They will soar up with wings as eagles. They will run, and not grow weary. They will walk, and not be faint.
