Even youths get tired and weary; even strong young men clumsily stumble. ¹ 

Do you not know? Have you not heard? The Lord is an eternal God, the creator of the whole earth. ¹  He does not get tired or weary; there is no limit to his wisdom. ² 

But those who wait for the Lord’s help ¹  find renewed strength; they rise up as if they had eagles’ wings, ²  they run without growing weary, they walk without getting tired.

A blacksmith works with his tool ¹  and forges metal over the coals. He forms it ²  with hammers; he makes it with his strong arm. He gets hungry and loses his energy; ³  he drinks no water and gets tired.
