Shemot - Exodus 30: 22-23
Exodus 30:23,a “And take for yourself choice spices, five hundred sheqels of liquid myrrh,…”
The word myrrh comes from the Hebrew word for Marar (maw-raw) meaning bitter.
Myrrh is a fragrant resin produced by bushes and trees covered with very long, very sharp thorns. To harvest myrrh one must fight through the thorns and pierce the bark and cause the precious liquid life source of the plant to ooze forth.
The resin that flows and hardens is referred to as "tears," because it forms into tear like shapes.
The myrrh that was of high quality was called the "Myrrh of Freedom" because it was that which flowed freely of itself, or when cut that which flowed from the wounds.
Myrrh has a fragrant aroma but is bitter to the taste.
