Exodus 27:1-3

1“You are to build an altar of acacia wood. The altar must be square, five cubits long, five cubits wide, and three cubits high.1 2Make a horn on each of its four corners, so that the horns are of one piece, and overlay it with bronze.

3Make all its utensils of bronze—its pots for removing ashes, its shovels, its sprinkling bowls, its meat forks, and its firepans.
