Exodus 38:1-7

¹He made the altar of burnt offering also of acacia wood; five cubits was its length, and five cubits its breadth; it was square, and three cubits was its height. ²He made horns for it on its four corners; its horns were of one piece with it, and he overlaid it with bronze. ³And he made all the utensils of the altar, the pots, the shovels, the basins, the forks, and the firepans: all its utensils he made of bronze. ⁴And he made for the altar a grating, a network of bronze, under its ledge, extending halfway down. ⁵He cast four rings on the four corners of the bronze grating as holders for the poles; ⁶he made the poles of acacia wood, and overlaid them with bronze. ⁷And he put the poles through the rings on the sides of the altar, to carry it with them; he made it hollow, with boards.
