Melachim Alef 7:31-33

Orthodox Jewish Bible

³¹ And the mouth [of the Mekhonah (Stand)] within the capital and above was a cubit; but the opening thereof was circular like the construction of the base, a cubit and an half; and also upon the rim of it were engravings. The frames were foursquare, not circular.

³² And under the frames were four ofanim (wheels); and the axles of the ofanim (wheels) were joined to the Mekhonah; and the diameter of each wheel was a cubit and half a cubit.

³³ And the construction of the ofanim (wheels) was like the construction of a merkavah ofan (wheel): their axles, and their hubs, and their rims, and their spokes, were all cast metal.
