Hackathon.Bible received this idea recently, and if you can help, please add a comment to help a brother out. Thank you.​

I have a suggestion for a hackathon project.

I would like to be able to cross reference Hebrew words and the Bible verses where they occur in the Hebrew Old Testament, and to cross reference Greek words and the Bible verses where they occur in the Greek New Testament and visa versa via the the Septuagint (Greek Old Testament).

I have not seen any online tools that do this.

That person goes on to describe the problem:

Go to the web page for the Greek New Testament word for oil, elaion.

Strong’s Concordance
: olive oil
Original Word: ἔλαιον, ου, τό
Part of Speech: Noun, Neuter
Transliteration: elaion
Phonetic Spelling: (el’-ah-yon)
Definition: olive oil
Usage: olive oil, oil.

As well as a definition, the occurrences of the word in the New Testament are listed. Great.

Also, there may possibly – not always – be a reference to the corresponding Hebrew word in the Old Testament:

Thayer’s Greek Lexicon
STRONGS NT 1637: ἔλαιον

ἔλαιον, ἐλαίου, τό (from Homer down), the Sept. chiefly for שֶׁמֶן, also for יִצְהָר; olive-oil: used for feeding lamps

Sept. is the abbreviation for Septuagint.

Now, try and look up the corresponding Hebrew words  שֶׁמֶן, and also יִצְהָר; and the associated Old Testament Bible verses. It’s difficult.
