'Contaminated' in the Bible

The priest is to have the woman stand in the LORD's presence, uncover her head, and put the grain offering as a memorial, a reminder of jealousy, into her hands. The priest is also to have in his hand the contaminated water that carries a curse.

"Then the priest is to write all of these words in a document and wipe it off with the contaminated water.

The woman is to drink the bitter water that brings a curse and the water that brings a curse is to be considered contaminated.

When he has had her drink the water, if she was defiled and had acted unfaithfully toward her husband, then the contaminated water that brings a curse will enter her and infect her, causing her abdomen to swell and her thigh to waste away. Then she is to be a cursed woman among her people.
