'Brim' in the Bible

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.

Under its brim were gourds encircling it ten to a cubit, completely surrounding the Sea; the gourds were in two rows, cast in one piece with it.

It was a hand width thick, and its brim was made like the brim of a cup, like a lily blossom. It held two thousand baths.
