Numbers 5:24KJV

22And this water that causeth the curse shall go into thy bowels, to make belly to swell, and thigh to rot: And the woman shall say, Amen, amen.

23And the priest shall write these curses in a book, and he shall blot out with the bitter water:

24And he shall cause the woman to drink the bitter water that causeth the curse: and the water that causeth the curse shall enter into her, bitter.

25Then the priest shall take the jealousy offering out of the woman's hand, and shall wave the offering before the LORD, and offer it upon the altar:

26And the priest shall take an handful of the offering, the memorial thereof, and burn upon the altar, and afterward shall cause the woman to drink the water.
