Scripture and the sphericity of the earth

Evidence of the earth's sphericity follows from the teaching of Moses himself, who stipulates (according to Philoponus) that the earth was initially entirely covered with water [Gen 1:2,9-10]. But for this to take place it would be necessary for its form to be spherical…Water tends to cover earth's sphere also in a symmetrical way, in a form of a sphere of larger diameter. According to Philoponus, the fact that earth was entirely covered by water necessities this theory, and so demonstrates earth's sphericity. E.
