'Walls' in the Bible

You are to overlay it with pure gold -- its top, its four walls, and its horns -- and make a surrounding border of gold for it.

You shall make two gold rings for it under its molding; you shall make them on its two side walls—on opposite sides—and they shall be holders for poles with which to carry it.

He overlaid it with pure gold -- its top, its four walls, and its horns -- and he made a surrounding border of gold for it.
