Moreover, Joshua, on dividing the land of Canaan amongst the tribes of Israel, made the tribes agree to ten conditions, the most important of which being the common use of the forests as pasture for cattle, and the common right of fishing in the Sea of Tiberias. Natural springs were to be used for drinking and laundry by all tribes, although the tribe to which the water course fell had the first rights. Prickly burnet ("Sarcopoterium spinosum") and the camelthorn ("Alhagi maurorum") could be freely collected as firewood by any member of any tribe, in any tribal territory.
