This statement amazes me. Greek discovery of a round earth? haha. Perhaps you mean verified by the Greeks through trigonometric means? Bible writers used the "language of appearance," just as people always have. Without it, the intended message would be awkward at best and probably not understood clearly To say the O.T. espouses flat earth is ridiculous. You have to take obvious poetical/allegorical sayings (some of which we still use today) such as "4 corners of the earth" or "sunrise" and "sunset" or "ends of the earth". Give me a break. Guess my local newspaper and local t.v. weatherman are flat-earthers, then. You have to deny so many obvious refs to get a flat earth: Job 26:7 Job 26:10 Isaiah 40:21-22 Proverbs 8:27 Luke 17:31 To suggest that people from Job's time through N.T. times could not observe a ship sail over the horizon or observe an eclipse shadow and not realize circularity is patently arrogant and smacks of an agenda. Pythagoras only used common sense observation - something the Greeks Roman conquerors did not accept.
