'Antimony' in the Bible

To the extent that I have been able to do so, I have provided supplies for the Temple of my God, including gold for what is to be made of gold, silver for what is to be made of silver, bronze for what is to be made of bronze, iron for what is to be made of iron, wood for what is to be made of wood, and great quantities of onyx, precious stones, antimony, colored stones, all types of other semi-precious stones, and plenty of marble.

"O afflicted one, passed back and forth, and not comforted, Look! I am about to set your stones in antimony, and lay your foundations with sapphires.
