So as a test I asked this service 'what is balm in Gilead' and it returned 4 other Bible sentences. Pressed 'Summarize', which unfolded comments on the 4 sentences and a summary of
'Overall, these passages present Gilead as a contested but fertile region east of the Jordan river. It was prized territory that was given to several Israelite tribes and seen as a divine provision. The name "Gilead" means "hill of testimony" referring to its choice lands. So the metaphor of "balm in Gilead" signifies the healing, restoration, and provision God can bring even in difficult times.'
My key observations:
1) The overall summary highly matches my own interpretations
2) Jer 8:22 was not referred - possibly because it does not define the concept, it just refers to its meaning
3) Inferring the summary from the 4 sentences is not easy but apparently AI can do so
I have a question on the generation of the overall summary: Is it based on on the 4 sentences only or does it include other biblical text behind the scenes?
