You, and the site you are linking to are reading into the bible in order to come to those conclusion. The wording is vague enough by today's terminology that you can easily do so but in the limited vocabulary of the time, it was sufficient enough to convey a correct understanding of the shape of the earth.<quoted text>
The Bible doesn't "teach" the world is flat, as in "Yea, verily, I sayeth unto you, the world is flat."
The Bible’s flat earth/solid sky dome universe
Flat is imposed by the reader's bias, you as well as anyone else making the claim of a flat earth is injecting their own bias into the translations. It really is that simple.
But, if you insist the bible teaches the world is flat, you should be able to find canon that echos this teaching. To date, there is absolutely none that I know of. But please, go right ahead and show me where there is some. There certainly was some for the geocentric earth hypothesis- that was also derived from people pretending to know and not the bible, but it is illustrative of how the early worshipers understood the world around them. No one believed the bible teaches a flat earth until recently when people like you attempted to pick through it and claim it was wrong. The only people who believe the bible teaches a flat earth are those trying to claim it is wrong.
Do you see a problem there? If not I can explain it to you. There is no flat earth until it was created by the very people trying to claim that because of it, the bible is flawed. This is like saying pluto is not a planet and all of astronomy before 1999 is wrong because of a vote on a definition in the mid 2000's. It's a fallacious argument put forth by ignorant people attempting to find flaws where they do not exist (and yes, there are flaws in the bible) in order to satisfy a need of their own.
