29 Giving to him that fainteth, strength, And to him that hath no vigour, he causeth, power to abound?30 Youths both faint and grow weary, And, young warriorsthey fall, they fall;31 But, they who wait for Yahweh, shall renew their strength, They shall mount on strong pinion like eagles,They shall run and not grew weary, They shall walk and not faint.
