This may perhaps be said to be the most perfect earthly shape of a plane (the 'cube' being perfection for a solid). See 'four' under NUMBFRS. It was the shape of the brazen altar, Ex 27:1; 38:1; the breastplate, Ex 28:16; 39:9; and the altar of incense, Ex 30:2; 37:25. Apparently it was the shape of the 'panels' of the base of the molten sea in Solomon's temple, 1Ki 7:31; also of the court of the future temple, Eze 40:47; the altar of the same, Eze 43:16; the portion of the land offered as a holy oblation, Eze 48:20; for the sanctuary, Eze 45:2; and for the city, Eze 48:16.
