Numbers 5:28

²⁶And the priest shall take a handful of the sacrifice as a memorial of it, and shall offer it up upon the altar; and afterward he shall cause the woman to drink the water.

²⁷And it shall come to pass, if she be defiled, and have altogether escaped the notice of her husband, then the water of the conviction that brings the curse shall enter into her; and she shall swell in her belly, and her thigh shall rot, and the woman shall be for a curse in the midst of her people.

— Numbers 5:28 —

²⁹This is the law of jealousy, wherein a married woman should happen to transgress, and be defiled;

³⁰or in the case of a man on whomsoever the spirit of jealousy should come, and he should be jealous of his wife, and he should place his wife before the Lord, and the priest shall execute toward her all this law.
