Bdellium

Fausset's Bible Dictionary

Βedolach (Genesis 2:12), a production of Havilah. Numbers 11:7; "The color of the manna was as the color of Bdellium." A gum exuding from a tree (the Borassus flabelliformis) in Arabia, India, and Babylonia, white and transparent, according to some; but this is hardly precious enough to be ranked with the gold and precious stones of Havilah. Others, a precious stone, crystal or beryl. This hardly suits Genesis 2:12, where "stone" is added to onyx, but not to it. Gesenius therefore takes it pearls, found abundant at the Persian gulf. This answers to the parallel comparison of manna to the white hoar frost on the ground (Exodus 16:14). Smith's Dictionary Appendix adheres to its being a gum.
