Frankincense

The word "frankincense" is "lebonah" in Hebrew and means "to be white". The word Lebanon is derived from the same root, because of its snowy white summits. And also the Hebrew word for "moon" is from the same root, because of its silvery whiteness.

Frankincense was poured on the bread as it lay there, being kept in a golden bowl alongside the table, together with other golden dishes and vessels for use in a drink offering. It was a resin obtained from Boswellia trees, one of the most highly valued incense gums with a beautiful fragrance of balsam. This frankincense constantly gave a pleasant fragrance to the Holy Place.

Pure Frankincense. The word "pure" here (tahor) is a different word than the one used with the gold (zachar). Zachar signifies the "intrinsic purity of nature, as contracted with uncleanness of nature; it is therefore used to designate beasts that are clean". Our word "tahor" indicates "a purity practically developed and manifested". Therefore pure gold speaks of purity of nature, where pure frankincense speaks of purity of ways.

Lev 24:7 "And you shall put pure frankincense on each row, that it may be on the bread for a memorial, an offering made by fire to the LORD."
