Jamb is an architectural term, defined as 'each of the side posts of a doorway, window, or chimney-piece, upon which rests the lintel; a cheek; esp., in popular use, (pl.) the stone sides or cheeks of a fire-place.' Its origin is less theological than prosaic: the French 'jambe', a leg; such vertical posts are seen as the 'legs' of the doorframe or mantelpiece.ACCESS_POST_ACTIONS
