Numbers 5:25-27

American Standard Version

²⁵ And the priest shall take the meal-offering of jealousy out of the woman’s hand, and shall wave the meal-offering before Jehovah, and bring it unto the altar: ²⁶ and the priest shall take a handful of the meal-offering, as the memorial thereof, and burn it upon the altar, and afterward shall make the woman drink the water. ²⁷ And when he hath made her drink the water, then it shall come to pass, if she be defiled, and have committed a trespass against her husband, that the water that causeth the curse shall enter into her and become bitter, and her body shall swell, and her thigh shall fall away: and the woman shall be a curse among her people.
