And, as I have pointed out, we have references like these;
Daniel 4:11
Upon my bed this is what
I saw; there was a tree at the center of the earth, and its height was great. The tree grew great and strong, its top reached to heaven,
and it was visible to the ends of the whole earth.
Isaiah 40:22
he that sitteth upon the circle of the earth, and the inhabitants thereof [are] as grasshoppers; that stretcheth out the heavens as a curtain, and
spreadeth them out as a tent to dwell in
If they are under the impression the whole earth was spherical then how would a tent cover it? No they saw their world in a 360 degree view. One can see how their god could spread his tent over the whole circle if you see in a 360 degree world view.
Job 38:13
That it might take hold of the ends of the earth, that the wicked might be shaken out of it?
What "ends of the earth"? If they new the earth was spherical they'd know it has no end. How do you shake one off or out of the earth unless you assume it's flat?
Job 11:9
Its measure is
longer than the earth, and
broader than the sea.
Deu 13:7
Any of the gods of the peoples that are around you, whether near you or far away from you,
from one end of the earth to the other
Josh 10:12-13
On the day when the LORD gave the Amorites over to the Israelites,
Joshua spoke to the LORD; and he said in the sight of Israel, "Sun, stand still at Gibeon, and Moon, in the valley of Aijalon." And the sun stood still, and the moon stopped, until the nation took vengeance on their enemies. Is this not written in the Book of Jashar? The sun stopped in midheaven, and did not hurry to set for about a whole day.
The verse above is a clear sign the people in your bible didn't know what they were talking about. The thought was that the earth was the center of the universe and the sun and moon revolved around it. Obviously they were in error.
