The large bronze basin, known as the Sea, replaced the smaller bronze washbasin used in the tabernacle (see Exodus 30:17–21). The Sea was made as one solid piece, except for the twelve bronze oxen it rested on. These oxen faced in four directions, three per direction, possibly symbolizing the priests' service to all twelve tribes of Israel. Later, Ahaz replaced the oxen with a stone base (2 Kings 16:17). Like the earlier washbasin, priests used the Sea for ceremonial washing (2 Chronicles 4:6) as they prepared to serve God (see Exodus 30:17–21). The difference in its water capacity (see 2 Chronicles 4:5) likely comes from varying measurement standards over time and place.
