Sorry. It clearly says circle. A circle is a circle and it is not a ball. It is impossible for a tent to completely cover a ball as the ball has many sides.
Like I said, only Jehovah’s Witnesses who are in the “truth” that try that argument with me. There is lots of stuff on many websites disputing Jehovah’s Witnesses that explain how the JWs attempt to misinterpret things including this section of the Bible.
Isaiah 40
22 It is he that sitteth upon the globe of the earth, and the inhabitants thereof are as locusts: he that stretcheth out the heavens as nothing, and spreadeth them out as a tent to dwell in.
A globe is not flat like a pancake as far as i know, as i said God knows how he created the earth.
Argue with God.
