Ezekiel 43:12-14 Common English Bible (CEB)
12 These are the instructions for the temple: the top of the mountain, as well as its boundaries all around, are most holy. These are the instructions for the temple.
13 These are the dimensions of the altar, according to a twenty-one-inch unit of measure.[a] The base is twenty-one inches high and twenty-one inches wide, with an outer curb measuring one and a half inches all around. This is the altar’s height. 14 From the base at ground level to the lower ledge is forty-two inches; the lower ledge is twenty-one inches wide. The distance from the lower to the upper ledge is seven feet; the upper ledge is twenty-one inches wide.
