Ezekiel 43:12-14 Christian Standard Bible (CSB)
12 This is the law of the temple: All its surrounding territory on top of the mountain will be especially holy. Yes, this is the law of the temple.
13 “These are the measurements of the altar in units of length (each unit being the standard length plus three inches):[a] The gutter is 21 inches[b] deep and 21 inches wide, with a rim of nine inches[c] around its edge. This is the base[d] of the altar. 14 The distance from the gutter on the ground to the lower ledge is 3½ feet,[e] and the width of the ledge is 21 inches. There are 7 feet[f] from the small ledge to the large ledge, whose width is also 21 inches.
