24He is to have the woman drink the bitter water that brings a curse, and it will enter her and cause her bitter suffering.
25The priest shall take from her hand the grain offering for jealousy, wave it before the LORD, and bring it to the altar.
26Then the priest is to take a handful of the grain offering as a memorial portion and burn it on the altar; after that he is to have the woman drink the water.
— Numbers 5:24-26
