'Sickness' in the Bible

If there be dearth in the land, if there be pestilence, if there be blasting, or mildew, locusts, or caterpillers; if their enemies besiege them in the cities of their land; whatsoever sore or whatsoever sickness there be:

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, Jehovah smote him in his bowels with an incurable sickness.

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.
