Job is a highly poetic book. To complain of such a figure of speech in a poetic book when today we hear the term "the four corners of the earth" is really reaching. Do you suppose anybody today who speaks of traveling the four corners of the earth really believes the earth is flat?
You are right about the dream in Daniel. It was a figurative description of a vision. And as far as the vision with Christ and the mountain, I think that just about everyone has understood that there was a vision involved. For one thing,if you go up to Mt Carmel, the highest mountain in the region, in that day you were not going to see anything but various Roman provinces of Palestine and Syria. But I don't see what the problem is. An account of a vision on a mountain is a long way from saying the earth is flat.
And no matter what the disagreement on what the Hebrew word in Isaiah 40:22 exactly means, it seems pretty clear that it does not say that the world is flat.
That may be so, but it also is not indicating that the earth is an oblate spheroid. Because the Bible isn't a science text.
