'Bowels' in the Bible

And thou shalt have great sickness by disease of thy bowels, until thy bowels fall out by reason of the sickness day by day.

And after all this the LORD smote him in his bowels with an incurable disease.

And it came to pass, that in process of time, after the end of two years, his bowels fell out by reason of his sickness: so he died of sore diseases. And his people made no burning for him, like the burning of his fathers.

And the LORD sent an angel, which cut off all the mighty men of valour, and the leaders and captains in the camp of the king of Assyria. So he returned with shame of face to his own land. And when he was come into the house of his god, they that came forth of his own bowels slew him there with the sword.
