The bible speaks of the Earth as a circle and a sphere is a type of a circle. As others have said, the bible isn't a detailed technical manual for the Earth or science etc.
I was researching the bible for descriptions earlier and found this:
Job 37:12 And it is turned round about by his counsels: that they may do whatsoever he commandeth them upon the face of the world in the earth.
"face of the world: is "פָּנִים (pânı̂ym) תֵּבֵל (têbêl)"
Face:
H6440
פָּנִים
pânı̂ym
paw-neem'
Plural (but always used as a singular) of an unused noun (פָּנֶה pâneh, paw-neh'; from 6437); the face (as the part that turns); used in a great variety of applications (literally and figuratively); also (with prepositional prefix) as a preposition (before, etc.): - + accept, a (be-) fore (-time), against, anger, X as (long as), at, + battle, + because (of), + beseech, countenance, edge, + employ, endure, + enquire, face, favour, fear of, for, forefront (-part), form (-er time, -ward), from, front, heaviness, X him (-self), + honourable, + impudent, + in, it, look [-eth] (-s), X me, + meet, X more than, mouth, of, off, (of) old (time), X on, open, + out of, over against, the partial, person, + please, presence, prospect, was purposed, by reason, of, + regard, right forth, + serve, X shewbread, sight, state, straight, + street, X thee, X them (-selves), through (+ -out), till, time (-s) past, (un-) to (-ward), + upon, upside (+ down), with (-in, + stand), X ye, X you.

So we have "the face of the world". On a persons head, the face is part of a roundish skull. Not perfectly round but it is spherical. Globalists (ball shaped) do not believe the Earth or any planet or moon is perfectly spherical just like FE does not deny there are valleys and mountains on a non-perfectly flat Earth.
Now, the very language of "the face of the world" strongly implies the bible is describing a spherical shaped Earth with a face or important part. If one was in heaven and looking at a distant Earth, the part "facing" heaven would be the "face of the world" but the rest of the world would still exist, just not visible until the Earth slowly rotates. That would be like a moving face and is still part of the rest of a sphere.
This is the strongest evidence of a spherical Earth in the bible using very colloquial language that most people at the time could understand since they knew people have a spherical head with a face in the front. The face can turn and so does the face of the world. Combine that with scripture that uses the term "circle" and the shape of the world is fairly clear.
