Numbers 5:26-28

Amplified Bible

²⁶ Then the priest shall take a handful of the grain offering as the memorial portion of it and offer it up in smoke on the altar, and afterward he shall make the woman drink the water. ²⁷ When he has made her drink the water, then it shall come about, that if she has defiled herself and has been unfaithful to her husband, the curse water will go into her and cause bitterness and cause her abdomen to swell and her thigh to waste away, and the woman will become a curse among her people. ²⁸ But if the woman has not defiled herself and is clean, then she will be free and conceive children.
