The Hebrew word for cinnamon is “kinamôn” which means to be erect or upright and has always been regarded as a deliciously fragrant substance and valued highly as a spice and perfume. Prov 7:17 “I have perfumed my bed with myrrh, aloes and cinnamon.”
Cinnamon was one of the principal ingredients used to make precious ointments. It was used as an ingredient in the Holy Anointing Oil as described in Exodus 30.
Symbolically, cinnamon points to the holiness of Jesus being upright and blameless in all He did.
