15 He cast two pillars of bronze. Eighteen cubits was the height of one pillar, and a line of twelve cubits measured its circumference. It was hollow, and its thickness was four fingers. The second pillar was the same.

23 Then he made the sea of cast metal. It was round, ten cubits from brim to brim, and five cubits high, and a line of thirty cubits measured its circumference.
