You must make the altar square—1 cubit [290] long and 1 cubit wide. It must be 2 cubits [291] high. There will be horns at the four corners. These horns must be made as one piece with the altar.
Make a horn for each of the four corners of the altar. Join each horn to its corner so that everything is one piece. Then cover the altar with bronze. [215]
Then take some of the bull’s blood and go to the altar. [270] Use your finger to put some blood on the horns of the altar. Pour all the blood that is left at the bottom of the altar.
