Ezekiel 43:12-16

This is the law of the house: its entire area on the top of the mountain all around shall be most holy. Behold, this is the law of the house. The Altar of Sacrifice

“And these are the measurements of the altar by cubits (the cubit being a cubit and a hand width): the base shall be a cubit and the width a cubit, and its border on its edge all around one span; and this shall be the height of the base of the altar.

And from the base on the ground to the lower ledge shall be two cubits, and the width one cubit; and from the smaller ledge to the larger ledge shall be four cubits, and the width one cubit.

The altar hearth shall be four cubits; and from the altar hearth shall extend upward four horns.

Now the altar hearth shall be twelve cubits long by twelve wide, square in its four sides.
