Numbers 5:25-27

Darby Translation

²⁵ And the priest shall take out of the woman's hand the oblation of jealousy, and shall wave the oblation before Jehovah, and shall present it at the altar.

²⁶ And the priest shall take a handful of the oblation as a memorial thereof, and burn it upon the altar; and afterwards he shall make the woman drink the water.

²⁷ And when he hath made her to drink the water, then it shall come to pass, if she have been defiled, and have committed unfaithfulness against her husband, that the water that bringeth the curse shall enter into her, for bitterness, and her belly shall swell, and her thigh shall shrink; and the woman shall become a curse among her people.
