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 xxviii) OR (matthew xiii))%((20 51) OR (c 51)) %2f sermons %((2f early) OR (((20 early) OR (10 early)))) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22bible %2f n.t %25 ((matthew xxviii) OR (matthew xiii))%((20 51) or (c 51)) %2f sermons %((2f early) or (((20 early) or (10 early)))) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %25 ((matthew xxviii) OR (matthew xiii))%((20 51) or (c 51)) %2f sermons %((2f early) or (((20 early) or (10 early)))) works to 1800%22*.
