What does it mean for Nabal’s heart to die within him so that he became as a stone?
1 Samuel 25:37 (ESV)
37In the morning, when the wine had gone out of Nabal, his wife told him these things, and his heart died within him, and he became as a stone.
It is not clear how to understand this expression. It could be figurative, in the sense that Nabal hardened himself further to any future dealings with David (see Exodus 15:16).1 It could also be that Nabal had some kind of a stroke which rendered him immobile until he passed away ten days later.2
