81 Sotah 3/1-3

(1) He would take her meal-offering from within the twisted basket and place it into a service-vessel, and put it into her hand. And the priest placed his hand underneath hers and waved it.

(2) He waved and brought it near, grabbed a handful and burned it, and the remainder was fed to the priests. He gives her to drink and after that sacrificed her meal-offering. R. Shimon said: He sacrificed her meal-offering and after that gave her to drink, as it says, "and after he shall give the woman the water to drink " (Numbers 5:26). If he gave her to drink and after that sacrificed her meal-offering, it is valid.

(3) If she said, "I will not drink [it]" before the scroll was erased, the scroll is archived, and her meal-offering is scattered on the ashes. Additionally, her scroll is not valid to be used with (lit. "to make drink") another suspected-adulteress. If the scroll was erased and she [only then] said, "I am impure," the water is spilled, and her meal-offering is scattered on the ashes. [However,] if the scroll was erased and she said, "I will not drink [it]," we force her mouth open and make her drink against her will.
