'Coals' in the Bible

The man shapes iron into a cutting tool and does his work over the coals, fashioning it with hammers and working it with his strong arm. He also gets hungry and his strength fails; he drinks no water and becomes weary.

No one recalls, nor is there knowledge or understanding to say, “I have burned half of it in the fire and also have baked bread over its coals. I roast meat and eat it. Then I make the rest of it into an abomination, I fall down before a block of wood!”

“Behold, I Myself have created the smith who blows the fire of coalsAnd brings out a weapon for its work;And I have created the destroyer to ruin.
