40:30 Even youths get tired and weary;
even strong young men clumsily stumble.
40:28 Do you not know?
Have you not heard?
The Lord is an eternal God,
the creator of the whole earth.
He does not get tired or weary;
there is no limit to his wisdom.
40:31 But those who wait for the Lord’s help
they rise up as if they had eagles’ wings,
they run without growing weary,
they walk without getting tired.
44:12 A blacksmith works with his tool
and forges metal over the coals.
He forms it
he makes it with his strong arm.
He gets hungry and loses his energy;
he drinks no water and gets tired.
