I am guessing the biblical parallels like
Acts 1:18
Now this man [Judas] purchased a field with the reward of iniquity; and falling headlong, he burst asunder in the midst, and all his bowels gushed out.
2 Chronicles 21:19
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.
Numbers 5:22
And this water that causeth the curse shall go into thy bowels, to make thy belly to swell, and thy thigh to rot: And the woman shall say, Amen, amen.
Acts 12:23
And immediately the angel of the Lord smote him, because he gave not God the glory: and he was eaten of worms, and gave up the ghost.

Isaiah 16:11
Wherefore my bowels shall sound like an harp for Moab, and mine inward parts for Kirharesh.
