The jawbone of a donkey said to have been wielded by the strongest man, Samson, blessed by the almighty. The jawbone was said to have been used by Samson to wipe out over a thousand trained soldiers equipped with the best armor, shield and sword. The jawbone negated all their defences and was used to strike the enemies down.
That was the weapon Samson had chosen after careful thought and so Goliath's sword was left untouched until Xena came up and picked up the sword.
Most that saw her do so, even while knowing about the insane strength she had, doubted that she would be able to fully use the power that the blade carried and their thoughts were almost proved right...
On picking up the great sword, Xena immediately knew that holding such a blade in real combat would be of a huge detriment to her but she still felt a strange affinity to the weapon.
