How would I find all of the instances in which Jesus healed or performed a miracle on the Sabbath?
There is a thread on miracles from which I derive {Label Miracle}. In Bible Search, type Jesus to see the suggestion for "Jesus Man, Supernatural ...", which gives you <Person Jesus>. If the two terms are related (or overlap), the INTERSECTS operator is needed:-
{Label Miracle} INTERSECTS <Person Jesus>
Run this search to get a few examples of healing on the Sabbath.
Then it's a matter of linking 'sabbath' to <Person Jesus>:
{Label miracle} INTERSECTS <Person Jesus> NEAR sabbath
This seems to be OK, but when you run it as a Bible Search it will miss Lk 14:4, because Sabbath is in verse 3. So run it as a Basic Search to override verse boundaries.
You might then replace NEAR with WITHIN 12 WORDS (or greater) to see if other results are included.
