Isaiah 40:29-31

Young's Literal Translation

²⁹ He is giving power to the weary, And to those not strong He increaseth might.

³⁰ Even youths are wearied and fatigued, And young men utterly stumble,

³¹ But those expecting Jehovah pass [to] power, They raise up the pinion as eagles, They run and are not fatigued, They go on and do not faint!
