Sirach 38:28

28  zThe smith also sitting by the anvil,

And considering the iron work,

The vapour of the fire wasteth his flesh,

And he fighteth with the heat of the furnace:

The noise of the hammer and the anvil is ever in his ears,

And his eyes look still upon the pattern of the thing that he maketh;

yHe setteth his mind to finish his work,

And ywatcheth to polish it aperfectly:
