the fruit of the olive tree
This tree yielded oil which was highly valued. The best oil was from olives that were plucked before being fully ripe, and then beaten or squeezed (Deuteronomy 24:20; Isaiah 17:6; 24:13). It was called “beaten,” or “fresh oil” (Exodus 27:20).
The phrase “vineyards and olives” (Judges 15:5, King James Version) should be simply “olive-yard,” or “olive-garden,” as in the Revised King James Version.
