Add context verses

[ArtskydJ]

I've got (or had) a test script that verifies that all the passages are sequential (or you change books).

However, sometimes this is not ideal.

Sometimes in the gospels, it would be nice to end a day with the same verse the next day:

For example, maybe Mark 100:23 has some context that would be nice for the end of Feb 30 and the start of Feb 31

Feb 30: Mark 100:1-23
Feb 31: Mark 100:23-50

Another (more concrete) example is Job.
Nov 19: Job 15:1-16
Nov 20: Job 15:17-35

On Nov 20, you don't know who is speaking. This is pretty important in the book of Job. Based on context, you can figure out it isn't Job, if you're aware of Job's position.

However, it would be nice to have Job 15:1 as context on Nov 20. So that's not just one verse earlier. It is many verses earlier.

Not every page will need context.
