Exodus 27:1-8

1“Build an altar of acacia wood, three cubits high; it is to be square, five cubits long and five cubits wide. 2Make a horn at each of the four corners, so that the horns and the altar are of one piece, and overlay the altar with bronze. 3Make all its utensils of bronze—its pots to remove the ashes, and its shovels, sprinkling bowls, meat forks and firepans. 4Make a grating for it, a bronze network, and make a bronze ring at each of the four corners of the network. 5Put it under the ledge of the altar so that it is halfway up the altar. 6Make poles of acacia wood for the altar and overlay them with bronze. 7The poles are to be inserted into the rings so they will be on two sides of the altar when it is carried. 8Make the altar hollow, out of boards. It is to be made just as you were shown on the mountain.
