And my 3rd example is in Revelation 21:21. It says, "The 12 gates were 12 pearls, each gate made of a single pearl. The great street of the city was of pure gold, like transparent glass." For thousands of years no person new what transparent glass was. However, people now put it in between the panes of the windows of aircraft windshields so that flying birds won't break the glass when they hit the windshields. Transparent gold makes windows very strong. You can read about it by Googleing it. This verse was written around 70-80 AD."
To add to the other comments: I'm a bit confused about the highlighted sentence. People already knew about transparent glass, according to wiki glass production goes back to 3500 BC in Mesopotamia. Around the time Revelation was written, the Romans had a big glass industry. If you ever visit Cologne in Germany, drop by the Römisch-Germanisches Museum. IIRC they even sell the original Roman glass bottles they dig up there, there are so many of them.
