Ezekiel 43:12-13

King James Version

¹² This is the law of the house; Upon the top of the mountain the whole limit thereof round about shall be most holy. Behold, this is the law of the house.

¹³ And these are the measures of the altar after the cubits: The cubit is a cubit and an hand breadth; even the bottom shall be a cubit, and the breadth a cubit, and the border thereof by the edge thereof round about shall be a span: and this shall be the higher place of the altar.
