12 This is the law of the temple: The whole territory on the top of the mountain all around shall be most holy. This is the law of the temple.
13 These are the measurements of the altar by cubits (the cubit is a cubit and a handbreadth): The base shall be a cubit, and the width a cubit, and its border by its edge all around shall be a span. And this shall be the height of the altar:
14 From the bottom on the ground even to the lower ledge shall be two cubits, and the width one cubit. And from the lesser ledge even to the greater ledge shall be four cubits, and the width one cubit.
15 So the altar shall be four cubits. And from the altar and upward shall be four horns.
16 The altar hearth shall be twelve cubits long by twelve wide, square in its four corners.
17 The ledge shall be fourteen cubits long and fourteen wide in the four squares. And the border about it shall be half a cubit. And its bottom shall be a cubit all around. And its stairs shall face east.
18 He said to me: Son of man, thus says the Lord God: These are the ordinances of the altar in the day when they shall make it to offer burnt offerings on it and to sprinkle blood on it.
