The problem is that these passages say nothing that would indicate a flat Earth.
Imagine living in a hole your entire life. You come out one day, and there in front of the hole is a copy of the Bible; you flip through it. Seeing a couple verses highlighted, you stop, you read them, you consider them.
Knowing nothing about anything, would you draw the conclusion from those few verses that the Earth is flat? Perhaps that the Earth does not move, even that it comes to an end somewhere (maybe like an arch), or you might assume it
is flat. That you can interpret the statement "end of the Earth" in many ways should be proof that its meaning is NOT intended to show the Earth as flat. Then again, the writers of the Bible had a habbit of beating around the bush.
Was this written in Hebrew? I believe Earth, land, country, etc. all use the same word. Perhaps this really means "end of the land." And in past times, even when it was believed the Earth to be spherical, many people in the area believed there to be land on only one side of it.
Arach? Perhaps you could add something to this
What is the original Hebrew of this text saying?
