Ezekiel 43:13

10 You, son of man, show the house to the house of Israel, that they may be ashamed of their iniquities; and let them measure the pattern.

11 If they be ashamed of all that they have done, make known to them the form of the house, and the fashion of it, and the exits of it, and the entrances of it, and all the forms of it, and all the ordinances of it, and all the forms of it, and all the laws of it; and write it in their sight; that they may keep the whole form of it, and all the ordinances of it, and do them.

12 This is the law of the house: on the top of the mountain the whole limit of it round about shall be most holy. Behold, this is the law of the house.

13 These are the measures of the altar by cubits (the cubit is a cubit and a handbreadth): the bottom shall be a cubit, and the breadth a cubit, and the border of it by the edge of it round about a span; and this shall be the base of the altar.

14 From the bottom on the ground to the lower ledge shall be two cubits, and the breadth one cubit; and from the lesser ledge to the greater ledge shall be four cubits, and the breadth a cubit.

15 The upper altar shall be four cubits; and from the altar hearth and upward there shall be four horns.

16 The altar hearth shall be twelve [cubits] long by twelve broad, square in the four sides of it.
