28. Havent you known? Havent you heard? The everlasting God, Yahweh, The Creator of the ends of the earth, doesnt faint. He isnt weary. His understanding is unsearchable.
29. He gives power to the weak. He increases the strength of him who has no might.
30. Even the youths faint and get weary, and the young men utterly fall;
31. But those who wait for Yahweh will renew their strength. They will mount up with wings like eagles. They will run, and not be weary. They will walk, and not faint.
- Isaiah 40:28-31 (WEB)
