Ezekiel 43:13-17

13“These are the measurements of the altar: There is a gutter all around the altar 21 inches deep and 21 inches wide, with a curb 9 inches wide around its edge. And this is the height of the altar:

14From the gutter the altar rises 3-1/2 feet to a lower ledge that surrounds the altar and is 21 inches wide. From the lower ledge the altar rises 7 feet to the upper ledge that is also 21 inches wide.

15The top of the altar, the hearth, rises another 7 feet higher, with a horn rising up from each of the four corners.

16The top of the altar is square, measuring 21 feet by 21 feet.

17The upper ledge also forms a square, measuring 24-1/2 feet by 24-1/2 feet, with a 21-inch gutter and a 10-1/2-inch curb all around the edge. There are steps going up the east side of the altar.”
