The word bedolach has been interpreted to signify both a white transparent oily gum, and a white pearl. Its colour is referred to in the description of the manna, Numbers 11:7 , and in Genesis 2:12 it is mentioned with gold and onyx stones as characterising the land of Havilah. The white pearl seems the more probable allusion, for the manna is in Exodus 16:14 compared also to the hoar frost.
