Make an acacia-wood altar. The altar should be square, seven and a half feet long and seven and a half feet wide. It should be four and a half feet high.
Make horns for the altar and attach them to it, one horn on each of its four corners. Cover it with copper.
Make pails for removing its ashes and its shovels, bowls, meat forks, and trays. Make all its equipment out of copper.
Make for the altar a grate made of copper mesh. Make four copper rings for each of the four corners of the mesh.
Slide the mesh underneath the bottom edge of the altar and then extend the mesh halfway up to the middle of the altar.
Make acacia-wood poles for the altar and cover them with copper.
Put the poles through the rings so that the poles will be on the two sides of the altar when it is carried.
Make the altar with planks but hollow inside. All these should be made just as you were shown on the mountain.
