Here’s what I use in my sermon notes and in book layouts:

\<(\d?|)\w*\d*:\d*~=*\d*

Break Down:
\< — Identify beginning of a word

(\d?|) — Identify book number if any (e.g. 3 John, 1 Kings, etc.)

\w*\d*:\d* — Identify any amount word characters followed by a single a single space, digit(s), colon, and digit(s)

~=*\d* — Identify a possible verse range with an en-dash followed by digit(s)
