Ezekiel 43:12-14 Living Bible (TLB)
12 And this is the basic law of the Temple: Holiness! The entire top of the hill where the Temple is built is holy. Yes, this is the primary law concerning it.
13 “And these are the measurements of the altar: The base is 21 inches high, with a 9-inch rim around its edge, and it extends 21 inches beyond the altar on all sides. 14 The first stage of the altar is a stone platform 3½ feet high. This platform is 21 inches narrower than the base block on all sides. Rising from this is a narrower platform, 21 inches narrower on all sides, and 7 feet high.
Ezekiel 43:12-14 New International Version (NIV)
12 “This is the law of the temple: All the surrounding area on top of the mountain will be most holy. Such is the law of the temple.
The Great Altar Restored
13 “These are the measurements of the altar in long cubits,[a] that cubit being a cubit and a handbreadth: Its gutter is a cubit deep and a cubit wide, with a rim of one span[b] around the edge. And this is the height of the altar: 14 From the gutter on the ground up to the lower ledge that goes around the altar it is two cubits high, and the ledge is a cubit wide.[c] From this lower ledge to the upper ledge that goes around the altar it is four cubits high, and that ledge is also a cubit wide.[d]
