Numbers 5:14-15

14And the spirit of jealousy shall come upon him, and he be jealous of his wife, and she be defiled: or if the spirit of jealousy shall come upon him, and he be jealous of his wife, and she be not defiled: 15Then shall the man bring his wife to the priest, and he 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 on it; for it is an offering of jealousy, an offering of memorial, bringing iniquity to remembrance.
