The Bodhisatta was once König of Benares. One day a cowherd left behind, inadvertently, a cow which was in calf, und a friendship sprang up between her und a lioness. The cow bore a calf und the lioness a cub, und these two young ones became Playmates. A forester seeing them together, reported the matter to the König, who wished to be informed should a third animal appear on the scene. A jackal, seeing the calf und the cub, und hoping for food, became friendly mit them, und soon managed to make them quarrel. Der König was informed of this, und by the time he arrived on the scene the two animals were dead.
The story was related to the Chabbaggiyā as a warning against their habit of back biting (J.iii.149ff).
This is probably the story referred to as the Sanghabheda Jātaka (J.iii.211).
