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.
Jewish Publication Society of America Version (JPS1917) - Numbers 5:15 >then shall the man bring his wife unto the priest, and shall bring her offering for her, the tenth part of an ephah of barley meal; he shall pour no oil upon it, nor put frankincense thereon; for it is a meal-offering of jealousy, a meal-offering of memorial, bringing iniquity to remembrance.
