'Rounded' in the Bible

The capitals on top of each pillar above the rounded latticework contained four cubits of lily designs,

The capitals on the two pillars were also immediately above the rounded surface next to the grating, and 200 pomegranates were in rows encircling each capital.

And the mouth of it within the crown and above was a cubit; and its mouth was rounded, as the work of the base, a cubit and a half; and also upon its mouth was sculpture; but their panels were square, not round.

The throne had six steps; there was a rounded top at the back of the throne, armrests on either side of the seat, and two lions standing beside the armrests.
