'Ivory' in the Bible

The king also made a large ivory throne, and he overlaid it [with] fine gold.

For the fleet of Tarshish belonged to the king [and was] on the sea with the fleet of Hiram; once every three years the fleet of Tarshish used to come carrying gold and silver, ivory, apes, and baboons.

The remainder of the acts of Ahab and all that he did, and the ivory palace and all the cities that he built, [are] they not written in the scroll of the events of the days of the kings of Israel?
