Numbers 5:22

And this water that causeth the curse
Upon the drinking of which the curse follows, if guilty:

shall go into thy bowels;
and there operate and produce the above effects, which are repeated again to inject terror:

to make [thy] belly to swell, and [thy] thigh to rot;
here ends the form of the oath, which begins ( Numbers 5:19 ) ;

and the woman shall say, amen, amen;
so be it; let it be as pronounced, if I am guilty; which, as Aben Ezra observes, is repeated for the sake of confirmation; though the Jewish writers commonly understand it as respecting various things, the oath and the curse, the thing charged with, and the persons suspected of ^F24.
