It happened about ten days after, that Yahweh struck Nabal, so that he died.
God struck Nabal dead for his pride and opposition to the Lord’s anointed. God would do the same to Saul for the same reasons. Nabal’s death undoubtedly encouraged David to believe that God would take vengeance on Saul. David’s experiences with Nabal were a microcosm of all that he had been enduring for so long with Saul, another fool. Saul admitted he was a fool in 1 Samuel 26:21.
