Isaiah 40
American Standard-ASV1901 (ASV)
29 Ref He giveth power to the faint; and to him that hath no might he increaseth strength.
30 Ref Even the youths shall faint and be weary, and the young men shall utterly fall:
31 Ref but they that wait for Jehovah shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; they shall walk, and not faint.
Bible in Basic English (BBE)
29 Ref He gives power to the feeble, increasing the strength of him who has no force.
30 Ref Even the young men will become feeble and tired, and the best of them will come to the end of his strength;
31 Ref 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.
