Those last two you posted didn't make any sense for a flat earth. I didn't get it. The first two I don't know, but when I get the chance I'll think about it some more.
Anyway, here's a place I know of in the Bible that speaks correctly about our earth and solar system (I know there's some others and I'll post them later, I'm a little tired at the moment).
"And the sun stood still, and the moon stayed, Until the nation had avenged themselves of their enemies. Is not this written in the book of Jashar? And the sun stayed in the midst of heaven, and hasted not to go down about a whole day." Joshua 10:13
I find this one very interesting. Even though I find it hard to believe (come on, that just sounds ridiculous), I can't scoff at the fact that if this was just made up, they knew this was no flat earth and that we are not the center of the universe. Notice the moon stayed still to. If the sun was rotating around the earth and this is what you suppose they believe, than if this was made up, why did they say the moon stopped to?
Here's my conclusion, if they did just make this up than they knew earth is not flat nor the center of the universe. Or, this really happened and he was just putting down what he observed.
Now, don't just say you have to take it 100% literally and the sun really stood still. It's written from an observation stand point. Do you believe there really is a SUNSET and SUNRISE when they say so on the weather?
Anyway, I've never really understood this flat earth stand point. If I were you, I wouldn't just go dismissing it because of some little detail. If you really went about trying to nut it out you would either nearly go insane or realise you misunderstood it and worked out what it means. The Bible is a bitch like that, I don't seem to be able to find anything to dissaprove or approve it upon. It just sits there in this neutral position freaking me out that it might be right. It's not fair, why can't things be more simple?
