God understandeth the way thereof, and he knoweth the place thereof. For he looketh to the ends of the earth, and seeth under the whole heaven; To make the weight for the winds; and he weigheth the waters by measure.
( Job 28:23-25 )
If you want to believe in flat earth no one is going to stop you. However nothing in the Bible, either in the meaning of words or the context of passages, requires you to believe that earth is flat and has an edge.
