The brazen laver was fashioned from the looking glasses of the woman who assembled at the door of the tabernacle.
The brazen laver, made from mirrors, and filled with water, is a type of mirror itself. It helps us come face to face with our selves.
At the reflecting waters of the laver, we are reminded, of our need for cleansing. We allow our sinful nature to be confronted by the spiritually cleansing Word, made active in our lives by our obedience to it.
Ephesians 5:26 further shows us that God's desire is for his church to be cleansed with the washing of water by the Word. The cleansing at the tabernacle was performed when the priests went to the water, and applied it. It is the same manner in which we are cleansed with the washing of water by /through the Word of God. We must let it touch us. We must apply it to our hearts and minds.
James 1:21 admonishes believers to receive the Word with meekness. We must submit to the Word of God. James 1:22-25 goes on to explain that the profit is in obeying the Word, rather than just hearing it. James compares it to looking in a mirror, seeing your face, then forgetting what you look like as soon as you walk away.
The priests had to minister daily in the tabernacle. They visited the brazen laver just as often. Likewise, after a believer's baptism in the saving name of Jesus Christ, we must not neglect the daily washing by the Word of God, "which is able to save your souls" (James 1:21).
