'Tragacanth' in the Bible

And they sat down to eat bread; and they lifted up their eyes and looked, and behold, a caravan of Ishmaelites came from Gilead; and their camels bore tragacanth, and balsam, and ladanum going to carry it down to Egypt.

And their father Israel said to them, If it is then so, do this: take of the best fruits in the land in your vessels, and carry down the man a gift: a little balsam and a little honey, tragacanth and ladanum, pistacia-nuts and almonds.
