29 He strengthens [DOU] those who feel weak and tired.

30 Even youths become faint and weary,

and young men will fall when they are exhausted.

31 But those who trust in Yahweh will become strong again;

it will be as though they will soar/fly high like [SIM] eagles do.

They will run for a long time and not become weary;

they will walk long distances and not faint.
