Commentary for I Kings 7:22

The top of the columns was designed like lilies. A half amoh at the top of each column each one’s wall was as thin as a lily, and for the rest of the column its thickness was four fingers [and it was] hollow.³⁶Alternatively, the lily work was not part of the pillar, but was attached to it after the pillar had been installed.—Metzudas Dovid. Therefore, this amoh was not counted in [the description] of the pouring [of the copper] for the columns in Divrei Hayomim because it was not similar to the work [of the rest] of the columns.
