And the priest shall set the woman before the LORD, and uncover the woman’s head, and put the offering of memorial in her hands, which is the jealousy offering: and the priest shall have in his hand the bitter water that causeth the curse:

After the priest has the woman stand before the LORD, he is to let down her hair and place in her hands the grain offering of memorial, which is the grain offering for jealousy. The priest is to hold the bitter water that brings a curse.
