Numbers 5:24-31

24 and hath caused the woman to drink the bitter waters which cause the curse, and the waters which cause the curse have entered into her for bitter things.
25 `And the priest hath taken out of the hand of the woman the present of jealousy, and hath waved the present before Jehovah, and hath brought it near unto the altar;
26 and the priest hath taken a handful of the present, its memorial, and hath made perfume on the altar, and afterwards doth cause the woman to drink the water:
27 yea, he hath caused her to drink the water, and it hath come to pass, if she hath been defiled, and doth commit a trespass against her husband, that the waters which cause the curse have gone into her for bitter things, and her belly hath swelled, and her thigh hath fallen, and the woman hath become an execration in the midst of her people.
28 `And if the woman hath not been defiled, and is clean, then she hath been acquitted, and hath been sown [with] seed.
29 `This [is] the law of jealousies, when a wife turneth aside under her husband, and hath been defiled,
30 or when a spirit of jealousy passeth over a man, and he hath been jealous of his wife, then he hath caused the woman to stand before Jehovah, and the priest hath done to her all this law,
31 and the man hath been acquitted from iniquity, and that woman doth bear her iniquity.'
