And he made ten bases of brass,.... Seats, stands, or settles for the ten lavers after mentioned:
four cubits was the length of one base, and four cubits the breadth thereof; as broad as it was long, and so a square, that the laver might stand firm upon it:
and three cubits the height of it; from the ground plates to the surface, that the priests might be able to reach the layers, and wash their sacrifices.
