Exodus 30:18

18. Laver of brass According to Exodus 38:8, it was made of the mirrors of the women who were wont to assemble at the entrance of the tabernacle . The purpose of this laver was mainly for the priests to wash themselves when they entered upon their holy work; also for the washing of inwards and legs of victims . Leviticus 1:9. Its form is not described, but it rested upon a foot or pedestal, and the adjoining cuts represent two possible forms according to which it may have been constructed . For the temple there was a brazen sea resting upon twelve oxen, and also ten lavers resting upon as many bases. See notes and cuts at 1 Kings 7:23-39. The laver was to be placed between the tabernacle… and the altar, probably as indicated in the cut of the tabernacle and court on page 522.
