Ezekiel 43:12-14 The Voice (VOICE)
12 Now here is My directive concerning the temple: the mountaintop and everything around the temple must be regarded as sacred ground. Pay strict attention to this directive concerning the temple.
13 The following measurements are the dimensions of the altar. They were taken with the long measure, which is 21 inches long. The gutter at the base of the altar is 21 inches deep and 21 inches wide and has a 9-inch rim around the edge of it. These are the heights of each part of the altar: 14 The altar rises from the ground 3½ feet to the lower ledge that is 21 inches wide; from there it rises an additional 7 feet to an upper ledge that is also 21 inches wide.
