Now he made the Sea (basin) of cast metal, ten cubits from brim to brim, circular in form, five cubits high and thirty cubits in circumference. [Ex 30:17-21; 2 Chr 4:6]

Then he made ten basins of bronze; each basin held forty baths and was four cubits, and there was one basin on each of the ten stands.
