I am the one who brought up the notion of a hebrew word for "ball" and I found the phrase,lo and behold in Isaiah.
Isa 22:18 He will surely violently turn and toss thee [like] a ball into a large country: there shalt thou die, and there the chariots of thy glory [shall be] the shame of thy lord's house.
This I found in the Blue Letter Bible and they show the phrase "thee [like] a ball" as 'duwr' in hebrew.
So it would appear they had the means to show a proper difference between circle and sphere.
