This is the example to use Random Bible Verse repo on github. It was 6 years ago when I was in Uni. There might be some spelling errors, because most of verses were typed into instead of copied into, and it was a fully local self sufficient JS script. No remote server, no remote API requests.
不要消灭圣灵的感动，不要藐视先知的讲论。但要凡事察验，善美的要持守，各样的恶事要禁戒不作。 ----帖撒罗尼迦前书5:19-22
