Numbers 5:26

And the priest shall take an handful of the offering, [even]
the memorial thereof
For good or evil, according as her works were, as Aben Ezra observes; a memorial for good, if innocent, and a memorial for evil, if guilty:

and burn [it] upon the altar;
as the handful of other meat offerings used to be, ( Leviticus 1:2 ) ;

and afterwards shall cause the woman to drink the water;
oblige her to it; having proceeded thus far, and no confession made, namely, an oath taken, the curses of it written in a scroll and scraped into the waters, and the jealousy offering waved and offered.
