Perhaps you should try some spelling variations:
matthew vii » matthew v
2f sermons » 2 sermons, 21 sermons, 24 sermons
2.1 early » 1.1 early, 11 early
2f early » 24 early, 20 early, 22 early
21 early » 11 early, 1.1 early
c 51 » c 1, c 5, _ 51

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 %2f ((matthew vii) OR (matthew xxv))%c 51 %2f sermons %((2f early) OR (((21 early) OR (2.1 early)))) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22bible %2f n.t %2f ((matthew vii) or (matthew xxv))%c 51 %2f sermons %((2f early) or (((21 early) OR (2.1 early)))) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %2f ((matthew vii) or (matthew xxv))%c 51 %2f sermons %((2f early) or (((21 early) OR (2.1 early)))) works to 1800%22*.
