הלבנה , Exodus 30:34 . Michablis makes the word a compound of הלב , milk or gum, (for the Syriac uses the noun in both senses,) and לבן , white, as being the white milk or gum of a plant. It is the thickened sap of an umbelliferous plant, called metopion, which grows on Mount Amanus, in Syria, and is frequently found in Persia, and in some parts of Africa. It was an ingredient in the holy incense of the Jews.
