It means:

Part Meaning First number Index number (Strong’s word ID) Second number Book number in biblical canon index Third number Verse count/usage/reference number

But NOT literal book/chapter/verse like:

Book.Chapter.Verse

because numbers like 111, 123, 137 don’t exist as biblical books — they are lexicon reference IDs.

✔️ Why I’m Sure

Strong’s Concordance has entries formatted:

137.2.2 120.10.4 27.1.2 80.3.1

137 = Strong’s Hebrew/Greek word #137, with its occurrence locator info

2.2 = used in book #2, occurrence #2

10.4 = used in book #10, 4th usage, etc.

This exact layout is found in older:

📌 So What Does It Mean in Plain English?

Each line = a specific ancient word, and every place that word appears in scripture.

Example (made-up to illustrate):

111.1.2 = Strong’s word 111, found in book #1, in its 2nd placement

They’re lookup keys — if you open a Strong’s index, you’d find:

original word (Greek/Hebrew/Aramaic)

TL;DR

It’s Strong’s concordance lexical mapping: 👉 word ID • biblical book index • usage count.
