Isaiah 44:12

44:12 A blacksmith works with his tool

and forges metal over the coals.

He forms it with hammers;

he makes it with his strong arm.

He gets hungry and loses his energy;

he drinks no water and gets tired.

Isaiah 57:10

57:10 Because of the long distance you must travel, you get tired,

but you do not say, ‘I give up.’

You get renewed energy,

so you don’t collapse.
