15 And the Ariel itself was four cubits: and from the Ariel upward were four horns.
16 And the Ariel was twelve cubits long, and twelve cubits broad, foursquare, with equal sides.
17 And the brim was fourteen cubits long, and fourteen cubits broad in the four corners thereof: and the crown round about it was half a cubit, and the bottom of it one cubit round about: and its steps turned toward the east.
18 And he said to me: Son of man, thus saith the Lord God: These are the ceremonies of the altar, in what day soever it shall be made: that holocausts may be offered upon it, and blood poured out.
19 And thou shalt give to the priests, and the Levites, that are of the race of Sadoc, who approach to me, saith the Lord God, to offer to me a calf of the herd for sin.
20 And thou shalt take of his blood, and shalt put it upon the four horns thereof, and upon the four corners of the brim, and upon the crown round about: and thou shalt cleanse, and expiate it.
21 And thou shalt take the calf, that is offered for sin: and thou shalt burn him in a separate place of the house without the sanctuary.
