The following is a function that I wrote to parse the Bible found on the Watchtower Online Library:
Aftering copying and pasting the above code into the JS console while visiting any page within the Watchtower Online Library, you can run the following code to actually parse the entire Bible:
Of course, due to the amount of chapters in the Bible, this process will take a few minutes so DO NOT LEAVE the Watchtower Online Library until an alert appears indicating the parsing has completed. This code is literally using your browser to navigate to each Bible chapter. Once done, an alert will appear on the page. I personally ran this code in Google Chrome. If this code doesn’t work for you, you may have to modify it especially if some time has passed since August 8th, 2017 (the time when I published this code).
