Exodus 27:1-8

“Using acacia wood, construct a square altar 7-1/2 feet wide, 7-1/2 feet long, and 4-1/2 feet high. Make horns for each of its four corners so that the horns and altar are all one piece. Overlay the altar with bronze. Make ash buckets, shovels, basins, meat forks, and firepans, all of bronze. Make a bronze grating for it, and attach four bronze rings at its four corners. Install the grating halfway down the side of the altar, under the ledge. For carrying the altar, make poles from acacia wood, and overlay them with bronze. Insert the poles through the rings on the two sides of the altar. The altar must be hollow, made from planks. Build it just as you were shown on the mountain.
