'Stomach' in the Bible

the priest will make the woman swear an oath of the sworn oath of the curse, the priest will say to the woman, "May Yahweh give you a curse and a sworn oath in the midst of your people with Yahweh making your hip fall away and your stomach swollen;

May this water that brings a curse enter your stomach, causing your belly to swell and your thigh to shrivel.’“And the woman must reply, ‘Amen, Amen.’

When he has made her drink the waters, it will come about, if she has defiled herself and acted unfaithfully to her husband and the waters of bitterness that bring a curse go into her and her stomach swells and her hip falls away, the woman will be as a curse in the midst of her people.

And went after the man of Israel into the tent, driving the spear through the two of them, through the man of Israel and through the stomach of the woman. So the disease was stopped among the children of Israel.
