Perhaps you should try some spelling variations:
matthew xxviii » matthew xxii, matthew xiii, matthew vii
2f sermons » 21 sermons, 24 sermons, 20 sermons
1720 early » 1727 early, 1820 early, 1770 early
20 early » 10 early, 1820 early
2c 51 » c 51, 20 51, 21 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 xxviii) OR (matthew xxv))%((2c 51) OR (24 51)) %((2f sermons) OR (2 sermons)) %((20 early) OR (1720 early)) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22bible %2f n.t %2f ((matthew xxviii) or (matthew xxv))%((2c 51) or (24 51)) %((2f sermons) or (2 sermons)) %((20 early) OR (1720 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %2f ((matthew xxviii) or (matthew xxv))%((2c 51) or (24 51)) %((2f sermons) or (2 sermons)) %((20 early) OR (1720 early)) works to 1800%22*.
