'Coals' in the Bible

“Whose collapse is like the smashing of a potter’s jar,Crushed so savagelythat there cannot be found among its pieces a potsherd [large enough]To take [coals of] fire from a fireplace,Or to scoop water from a cistern.”

The smith with the tongs both worketh in the coals, and fashioneth it with hammers, and worketh it with the strength of his arms: yea, he is hungry, and his strength faileth: he drinketh no water, and is faint.

Half the wood he burns in the fire, and over that half he places meat so he can eat. He sits by its coals, warms himself, and says, "Ah! I am warm in front of the fire."

And none considereth in his heart, neither is there knowledge nor understanding to say, I have burned part of it in the fire; yea, also I have baked bread upon the coals thereof; I have roasted flesh, and eaten it: and shall I make the residue thereof an abomination? shall I fall down to the stock of a tree?

"See, they are just like stubble; fire burns them up. They could not even save themselves from the power of the flame. There will be no coals for warming oneself, no fire to sit by.

Behold, I have created the smith that bloweth the coals in the fire, and that bringeth forth an instrument for his work; and I have created the waster to destroy.
