Bhishma vowed to kill Subala and his family. He locked them in prison, giving them only a handful of rice each day.
Subala's sons fought over the rice, but Subala ordered them to give it all to Shakuni. "He is the most clever," said Subala. "He must live to avenge us." Subala then broke Shakuni's ankle. "When you limp," he said, "remember us."
Later, as he was dying, Subala said, "Make my knucklebones into dice. Those dice will do your bidding."
Shakuni alone survived. He then lived in Hastinapura with Gandhari, but he nursed hatred for Bhishma in his heart.
