The jealous husband brought his suspected wife before the priest, with her offering of barley meal, without oil or frankincense, in her hand
The priest took holy water in an earthen vessel in his hand and sprinkled it with the dust of the floor. Then the priest administered the oath to her. If she confessed to guilt she was compelled to drink the water, and stood accursed. If otherwise, she was allowed to go free (Num. 5:12-31).
