Numbers 5:26-28

Complete Jewish Bible

²⁶ The cohen is to take a handful of the grain offering as its reminder portion and make it go up in smoke on the altar; afterwards, he is to make the woman drink the water. ²⁷ When he has made her drink the water, then, if she is unclean and has been unfaithful to her husband, the water that causes the curse will enter her and become bitter, so that her abdomen swells and her private parts shrivel up; and the woman will become an object of cursing among her people. ²⁸ But if the woman is not unclean but clean, then she will be innocent and will have children.
