Perhaps you should try some spelling variations:
2f sermons » 2 sermons, 21 sermons, 24 sermons
25 matthew » 15 matthew, 2 matthew, 22 matthew
2f matthew » 2 matthew, 22 matthew, _ matthew
20 early » 10 early, 1820 early, 1720 early
22 early » 2 early, 12 early, 1722 early
2f early » 21 early, ef early, f early
2c 51 » 24 51, 20 51, 21 51
c 51 » c 1, c 5, _ 51

Try widening your search to All Fields.

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) OR (25 matthew)) xxviii%((2c 51) OR (c 51)) %2f sermons %((((2f early) OR (22 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 %((2f matthew) OR (25 matthew)) xxviii%((2c 51) or (c 51)) %2f sermons %((((2f early) or (22 early))) or (20 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %((2f matthew) OR (25 matthew)) xxviii%((2c 51) or (c 51)) %2f sermons %((((2f early) or (22 early))) or (20 early)) works to 1800%22*.
