Heart Failure

1 Samuel 25:37
Then in the morning, when Nabal was sober, his wife told him all these things, and his heart failed him and he became like a stone.

We go ahead a few chapters here, and for once, heart means a hollow, muscular organ in the thorax which maintains the circulation of the blood through the blood vessels.
David is still living with his men out in the desert, and he had the unfortunate
run-in with Nabal, whose very name means fool. David lost his temper then set out to avenge himself for the slight.
Of course, beautiful and wise Abigail saved both men, though Nabal didn't know it until next day. And there is an emotional component here. The shock of hearing how close he had come to death actually killed him.
And the next marriage was David and Abigail.
