Sirach 38:28

Geneva(i) 28 The smith in like maner abideth by his anuill, and doeth his diligence to labour the yron: the vapour of the fire dryeth his flesh, and hee must fight with the heate of the fornace: the noyse of the hammer is euer in his eares, and his eyes looke still vpon the thing that he maketh: he setteth his minde to make vp his workes: therefore he watcheth to polish it perfectly.
