Occurs only in Gen. 2:12, where it designates a product of the land of Havilah; and in Num. 11:7, where the manna is likened to it in colour. It was probably an aromatic gum like balsam which exuded from a particular tree (Borassus flabelliformis) still found in Arabia, Media, and India. It bears a resemblance in colour to myrrh. Others think the word denotes “pearls,” or some precious stone.
