Frankincense is in six passages (Isa 43:23; 60:6; 66:3; Jer 6:20; 17:26; 41:5) mistranslated in AV 'incense,' but correctly in RV. It is a sweet-smelling gum, obtained as a milky exudation from various species of Boswellia, the frankincense tree, an ally of the terebinth. The gum was imported from S. Arabia (Isa 60:6; Jer 6:20); it was a constituent of incense (Ex 30:34); it is often associated with myrrh (Song 3:6; 4:6; Mt 2:11); it was offered with the shewbread (Le 24:7).
