"You are to construct the altar of acacia wood. The altar must be square, seven and a half feet long, and seven and a half feet wide; it must be four and a half feet high.
Make horns for it on its four corners; the horns are to be of one piece. Overlay it with bronze.
Make its pots for removing ashes, and its shovels, basins, meat forks, and firepans; make all its utensils of bronze.
Construct a grate for it of bronze mesh, and make four bronze rings on the mesh at its four corners.
Set it below, under the altar's ledge, so that the mesh comes halfway up the altar.
Then make poles for the altar, poles of acacia wood, and overlay them with bronze.
The poles are to be inserted into the rings, so that the poles are on two sides of the altar when it is carried.
Construct the altar with boards so that it is hollow. They are to make it just as it was shown to you on the mountain.
