You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %22bible %2f n.t %((25 matthew) OR (2 matthew)) xxviii%((21 51) OR (24 51)) %((2f sermons) OR (21 sermons)) %((2f early) OR (20 early)) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22bible %2f n.t %((25 matthew) OR (2 matthew)) xxviii%((21 51) or (24 51)) %((2f sermons) or (21 sermons)) %((2f early) or (20 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %((25 matthew) OR (2 matthew)) xxviii%((21 51) or (24 51)) %((2f sermons) or (21 sermons)) %((2f early) or (20 early)) works to 1800%22*.
