Ezekiel 43:12-15 The Message (MSG)
12 “This is the law of the Temple: As it radiates from the top of the mountain, everything around it becomes holy ground. Yes, this is law, the meaning, of the Temple.
13-14 “These are the dimensions of the altar, using the long (twenty-one-inch) ruler. The gutter at its base is twenty-one inches deep and twenty-one inches wide, with a four-inch lip around its edge.
14-15 “The height of the altar is three and a half feet from the base to the first ledge and twenty inches wide. From the first ledge to the second ledge it is seven feet high and twenty-one inches wide. The altar hearth is another seven feet high. Four horns stick upward from the hearth twenty-one inches high.
