1. Make an acacia-wood altar for burning incense.
2. The altar should be square, eighteen inches long and eighteen inches wide. It should be three feet high. Its horns should be permanently attached.
3. Cover the altar with pure gold, including its top, all its sides, and its horns. You should also make a gold molding all around it.
4. Make two gold rings and attach them under the molding on two opposite sides of the altar. They will house the poles used to carry the altar.
