'Bowels' in the Bible

and this water that brings a curse shall go into your stomach, and make your abdomen swell and your thigh waste away.” And the woman shall say, “Amen. Amen (so let it be).”

But Amasa [who had replaced Joab as David’s commander] was off guard and not attentive to the sword in Joab’s hand. So Joab struck Amasa in the abdomen with the sword, spilling his intestines to the ground. Without another blow Amasa died. Then Joab and Abishai his brother pursued Sheba the son of Bichri.

and you will suffer a severe illness, an intestinal disease, until your intestines come out because of the sickness, day after day.’”

Now it came about in the course of time, at the end of two years, that his intestines came out because of his disease and he died in excruciating pain. And his people did not make a funeral fire to honor him, like the fire for his fathers.
