'Ivory' in the Bible

And the king made a great throne of ivory, and overlaid it with refined gold:

For the king had on the sea a Tarshish-fleet, with the fleet of Hiram: once in three years came the Tarshish-fleet, bringing gold and silver, ivory, and apes, and peacocks.

And the rest of the acts of Ahab, and all that he did, and the ivory house that he built, and all the cities that he built, are they not written in the book of the chronicles of the kings of Israel?
