15 Now the hearth itself was four cubits. And from the hearth going upward, there were four horns.
16 And the hearth was twelve cubits in length by twelve cubits in width, foursquare, with equal sides.
17 And the rim was fourteen cubits in length, by fourteen cubits in width, at its four corners. And the crown all around it was one half cubit, and its bend was one cubit all around. And its steps turned toward the east.
18 And he said to me: "Son of man, thus says the Lord God: These are the rituals of the altar, in whatever day it will be made, so that holocausts may be offered upon it, and blood may be poured out.
19 And you shall present these to the priests and to the Levites, who are of the offspring of Zadok, those who draw near to me, says the Lord God, so that they may offer to me a calf from the herd on behalf of sin.
20 And you shall take from its blood, and you shall place it on its four horns, and on the four corners of the rim, and on the crown all around. And so shall you cleanse and expiate it.
21 And you shall take the calf, which will be offered for sin, and you shall burn it in a separate place in the house, outside of the sanctuary.
