Ezekiel 43:13-17

13And 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 of it by its edge on every side shall be a span: and this shall be the higher place of the altar.12 14And from the bottom upon the ground even to the lower ledge shall be two cubits, and the breadth one cubit; and from the smaller ledge even to the greater ledge shall be four cubits, and the breadth one cubit. 15So the altar shall be four cubits; and from the altar and upward shall be four horns.34 16And the altar shall be twelve cubits long, twelve broad, square in its four sides. 17And the ledge shall be fourteen cubits long and fourteen broad in its four sides; and the border about it shall be half a cubit; and the bottom of it shall be a cubit about; and its stairs shall look toward the east.
