Ezekiel 43:12-14 Complete Jewish Bible (CJB)
12 This is Torah for the house: the whole surrounding area on the mountaintop will be especially holy. This is Torah for the house.”
13 These are the measurements of the altar in cubits (a cubit here is defined as a normal cubit [eighteen inches] plus a handbreadth [three inches]): the base, one cubit [twenty-one inches] deep and one cubit wide; with the molding surrounding it at its rim about a hand-span [nine inches] in width. The height of the altar is thus: 14 from the base on the ground to the lower ledge, three-and-a-half feet, with the width twenty-one inches; from the lower ledge to the upper ledge, seven feet, with the width again twenty-one inches.
