Why are the dimensions of the laver not given in Exodus?

The absence of dimensions for the laver in Exodus 30 can be interpreted as a theological statement about the boundless nature of God's provision for our cleansing. Unlike other pieces of furniture in the tabernacle, which have exact measurements, the laver's unspecified size reflects that God's grace and the means of purification through His Word are boundless and available to all His people. This signifies that there are no limits to how often we can come for cleansing and that God's Word is always accessible for our spiritual needs.
