I would argue, no, though they certainly didn’t consider it to be spherical either, at least before the Greeks. Rather, they simply didn’t think about it. Most likely, the inhabitants of the ANE were indifferent to the shape of the planetary earth, for such a concept did not exist to them. There is no Hebrew word for Earth in the Planetary sense, the closest thing being the word ‘Tebhel’ (world), which even is usually used in a political sense. The word ‘Eretz’ (earth) actually refers to land, and is actually distinguished from the sea in Genesis 1. It is only in our modern day worldview that we think of the word ‘earth’ as referring to the whole world.
So whilst the Biblical writers (at least those of the OT) had no knowledge that the earth was round or orbiting the sun. It is problematic for us as ECs to assert that the Bible claims that the earth is flat and unmoving. For in all truth, they didn’t, and they had no means of saying so. The phrase ‘Circle of the Earth’ refers to the single circular continent, not to the planet.
What do you think?
