(ii) Lebownah (3828) - frankincense (from its whiteness or perhaps that of its smoke): -frank-) incense. From root meaning 'white'.
Frankincense was part of the sacred anointing oil <Ex. 30:34>. It was used in sacrificial offering <Lev. 2:1>, as a fumigant during animal sacrifices <Ex. 30:7>, and as perfume <Song 3:6>. It was a gift to baby Jesus <Matt. 2:11>.
The trees are native to India, Arabia, and Africa. Palestine probably obtained this product through foreign trade <Is. 60:6>.
