“The smith with the tonges both worketh in the coales, and fashioneth it with hammers, and worketh it with the strength of his armes: yea he is hungrie, and his strength faileth; hee drinketh no water, and is faint.”
1611 King James Version (KJV)
44:12 Faint - This is mentioned as an evidence of great zeal and industry in carrying on this work; so that they forget or neglect to eat and drink.
