'Folding doors' in the Bible

And the two folding-doors were of cypress-wood: the two leaves of the one door were folding, and the two leaves of the other door were folding.

and the basons, and the knives, and the bowls, and the cups, and the censers of pure gold; and the hinges of gold, for the folding-doors of the inner house, the most holy place, and for the doors of the house, of the temple.

and the knives, and the bowls, and the cups, and the censers, of pure gold; and the entrance of the house, the inner folding-doors thereof for the most holy place, and the doors of the house, of the temple, of gold.
