Discussion
Although its identity in the Bible is uncertain, galbanum is probably a gum resin from a plant called Fennel Ferula galbaniflua, which grows in India, Iran and Afghanistan, and especially in the high mountains of Iran. The fennel is related to the parsley family. Today most commercial galbanum comes from Lebanon and Iran.

Special significance
Translation
Since fennel is not well known, most translators will need to transliterate from a major language. Some possibilities are:
1. transliteration from Hebrew: helibena, elbenahi, lebena;
2. transliteration from Latin via English: galbanum;
3. substitution of a local type of gum, adding chelbenah or galbanum as a tag or in a footnote.
4. transliteration of the name of the plant with a classifier: gum of ferula (French), feneli (English), hinojo /ferula (Spanish).
