The bronze altar, brazen altar, table of the Lord or altar of sacrifice, altar of burnt offering  was an altar built for sacrificial purposes. The literal meaning of the Hebrew term is "place of slaughter" or "place of sacrifice". The altar was a central point of the religious worship. It had horns to which the animal to be sacrificed could be bound. This altar differed in construction, size, etc.. at different times.

It was made of acacia wood overlaid with bronze. The altar had a horn on each of the four corners, so that the horns and the altar formed a single piece.
