Numbers 5:11-15

11And Jehovah spake unto Moses, saying, 12Speak unto the children of Israel, and say unto them, If any man’s wife go aside, and commit a trespass against him, 13and a man lie with her carnally, and it be hid from the eyes of her husband, and be kept close, and she be defiled, and there be no witness against her, and she be not taken in the act; 14and the spirit of jealousy come upon him, and he be jealous of his wife, and she be defiled: or if the spirit of jealousy come upon him, and he be jealous of his wife, and she be not defiled: 15then shall the man bring his wife unto the priest, and shall bring her oblation 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.
