'Plates' in the Bible

Plates of gold were put all through the house till it was covered completely (and the altar in the inmost room was all covered with gold).

Every base had four wheels of brass, turning on brass rods, and their four angles had angle-plates under them; the angle-plates under the base were of metal, and there were ornaments at the side of every one.

And there were four angle-plates at the four angles of every base, forming part of the structure of the base.
