Priests: Services of Deciding in Cases of Jealousy
Source: TTT
Numbers 5:14, 15
and if a feeling of jealousy comes over her husband and he suspects his wife who has defiled herself—or if a feeling of jealousy comes over him and he suspects her even though she has not defiled herself— / then he is to bring his wife to the priest. He must also bring for her an offering of a tenth of an ephah of barley flour. He is not to pour oil over it or put frankincense on it, because it is a grain offering for jealousy, an offering of memorial as a reminder of iniquity.
