40:29 He gives strength to those who are tired;

to the ones who lack power, he gives renewed energy.

40:30 Even youths get tired and weary;

even strong young men clumsily stumble.56

40:31 But those who wait for the Lord’s help57 find renewed strength;

they rise up as if they had eagles’ wings,58

they run without growing weary,

they walk without getting tired.
