The purpose of the Bible is to reveal God’s love, specifically through Jesus Christ. It is because of Jesus’ death and resurrection from the dead that we can be restored to a personal relationship with God. Only through the name of Jesus. (Acts 4:12) Another way God has proved His love is by the creation of healing plants. When He created the world and everything in it (Psalms 104:5) He created plants that have healing properties and caused them to grow all over the world. He knew we would need help with healing all these years later. What a kind loving thing to do!
Although the Bible does not explain how aromatic oils were used in those days, except for the holy anointing oil and the holy incense, it does mention aromatic oils, and plants often. The very first mention of aromatic plants is in the very beginning of the Bible, the second chapter, twelfth verse.
Most scholars agree that Moses wrote the book of Genesis even though he lived much later. God spoke directly to Moses often so He probably told Moses what to write. When he is describing exactly where the Garden of Eden used to be he said, “The gold of that land is good; the bdellium and the onyx stone are there.” Gold we know, onyx we know (very black stone often used in jewelry), but what is bdellium? It is the non-scientific name for the family of plants called Burseraceae.
Back in the day…in the 1700’s Carolus Linnaeus invented a system for categorizing all living things. Over the years, as more knowledge has been acquired the system has changed some. Every living thing has two parts to its name, genus and species. The genus is comparable to our last names and the species is comparable to our first names. (In America) The next category is the “family”. …All that to explain that frankincense and myrrh both belong to the Burseraceae family.
The second time aromatic plants are mentioned is in Genesis 37:25 where we read the story about how Josephs own brothers sold him as a slave to myrrh merchants that were passing by. In those days there was a regular trade route from Arabia and Egypt to the north through the land of Canaan.
