“Abigail came to Nabal. He was holding a feast in his house, like the feast of a king. Nabal’s heart was merry within him, for he was very drunk. So she told him nothing at all until the morning light. In the morning, when the wine had gone out of Nabal, his wife told him these things. Then his heart died within him. He became like a stone. About ten days later, Yahweh struck Nabal and he died.”
Abigail did not tell Nabal about her encounter with David. The next day, after Nabal had sobered up after the drunken feast he had the night before, she told him what had happened. His heart hardened and became like a stone. 10 days later, Yahweh struck him and he died. This tough guy died a tough death.
