Ezekiel 43:13

10 Thou, 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 And if they be ashamed of all that they have done, make known unto them the form of the house, and the fashion thereof, and the egresses thereof, and the entrances thereof, and all the forms thereof, and all the ordinances thereof, and all the forms thereof, and all the laws thereof; and write it in their sight; that they may keep the whole form thereof, and all the ordinances thereof, and do them.

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

14 And from the bottom upon 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 And the upper altar shall be four cubits; and from the altar hearth and upward there shall be four horns.

16 And the altar hearth shall be twelve [cubits] long by twelve broad, square in the four sides thereof.
