A good name is better than precious oil (Ecclesiastes 7:1).
This picture shows jugs, likely for exporting fine oil. These jugs are Cypro-Phoenician and date to the 11th–8th centuries BC. Solomon’s lifetime is within this range of time and he traded with Phoenicia, so Solomon may very well have seen jugs like these filled with precious oil. This photograph was taken at the Hecht Museum at the University of Haifa.
