Albert Barnes Commentary 2 Chronicles 4:5

"And it was a handbreadth thick; and the brim thereof was wrought like the brim of a cup, like the flower of a lily: it received and held three thousand baths." — 2 Chronicles 4:5 (ASV)

Three thousand baths - See the note on 1 Kings 7:23. It is quite possible that the text in either this passage or in Kings has been accidentally corrupted.
