Bezalel constructed the altar of burnt offering from acacia wood. It was square, seven and a half feet long and seven and a half feet wide, and was four and a half feet high.
He made horns for it on its four corners; the horns were of one piece. Then he overlaid it with bronze.
He made all the altar's utensils: the pots, shovels, basins, meat forks, and firepans; he made all its utensils of bronze.
He constructed for the altar a grate of bronze mesh under its ledge, halfway up from the bottom.
At the four corners of the bronze grate he cast four rings as holders for the poles.
He also made the poles of acacia wood and overlaid them with bronze.
Then he inserted the poles into the rings on the sides of the altar in order to carry it with them. He constructed the altar with boards so that it was hollow.
