Large basin or bowl used in purification rites. The OT describes the lavers used in the tabernacle and  in Solomon’s temple. The bronze laver of the tabernacle was constructed from metal mirrors provided by the women who ministered at the tabernacle entrance (Exod 38:8). The priests used the laver for washing their hands and feet before priestly service (Exod 30:18; 40:30-31). Levites also used water from this laver to purify

themselves (Num 8:7). Solomon’s temple employed a large laver, the molten sea (1 Kings 7:23-26; 2 Chron 4:2-5), and 10 smaller lavers (1 Kings 7:38-39; 2 Chron 4:6). The priests washed in the molten sea. The 10 lavers were used for washing sacrifices (2 Chron 4:6).
