Isaiah 40:29-31

New American Standard Bible

²⁹ He gives strength to the ^(A)weary,
And to the one who lacks might He ^(B)increases power.
³⁰ Though ^(C)youths grow weary and tired,
And vigorous ^(D)young men stumble badly,
³¹ Yet those who ^[a]wait for the Lord
Will ^(E)gain new strength;
They will ^[b](F)mount up with wings like eagles,
They will run and not get tired,
They will walk and not become weary.
