12This 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.
13And 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.
14And 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.
15And the upper altar shall be four cubits; and from the altar hearth and upward there shall be four horns.
16And the altar hearth shall be twelve [cubits] long by twelve broad, square in the four sides thereof.
17And the ledge shall be fourteen [cubits] long by fourteen broad in the four sides thereof; and the border about it shall be half a cubit; and the bottom thereof shall be a cubit round about; and the steps thereof shall look toward the east.
18And he said unto me, Son of man, thus saith the Lord Jehovah: These are the ordinances of the altar in the day when they shall make it, to offer burnt-offerings thereon, and to sprinkle blood thereon.
