Revelation 20:9 says
“They went up onto the breadth of the earth and surrounded the camp of the saints and the beloved city.”
We are looking into the word “breadth”. The word “breadth” comes from the greek word Platos which also comes from the greek word Platus. This means “spreads out- flat.” Therefore Revelation 20:9 says that the earth is flat.
But, since this part of Revelation is talking about the battle of Armageddon, some argue that it is saying that this one specific place is flat, therefore still allowing for there to be curvature to the earth. But, Job 38:18 says,
“Have you comprehended the breadth of the earth? Tell me if you know all this.”
This is the LORD talking to Job in reference to the earth. Not just one small place on the earth but the whole earth. Therefore saying that the earth is, “spread out-flat”. Scripture says the earth is flat.
