Numbers 5:28

24 He is to have the woman drink the bitter water that brings a curse, and it will enter her and cause her bitter suffering.

25 The priest shall take from her hand the grain offering for jealousy, wave it before the LORD, and bring it to the altar.

26 Then the priest is to take a handful of the grain offering as a memorial portion and burn it on the altar; after that he is to have the woman drink the water.

27 When he has made her drink the water, if she has defiled herself and been unfaithful to her husband, then the water that brings a curse will enter her and cause bitter suffering; her belly will swell, her thigh will shrivel, and she will become accursed among her people.

28 But if the woman has not defiled herself and is clean, she will be unaffected and able to conceive children.

29 This is the law of jealousy when a wife goes astray and defiles herself while under her husband’s authority,

30 or when a feeling of jealousy comes over a husband and he suspects his wife. He is to have the woman stand before the LORD, and the priest is to apply to her this entire law.

31 The husband will be free from guilt, but the woman shall bear her iniquity.”
