Numbers 5:11-15

11And the Lord spoke to Moses, saying,

12“Speak to the children of Israel, and say to them: ‘If any man’s wife goes astray and behaves unfaithfully toward him,

13and a man lies with her carnally, and it is hidden from the eyes of her husband, and it is concealed that she has defiled herself, and there was no witness against her, nor was she caught—

14if the spirit of jealousy comes upon him and he becomes jealous of his wife, who has defiled herself; or if the spirit of jealousy comes upon him and he becomes jealous of his wife, although she has not defiled herself—

15then the man shall bring his wife to the priest. He shall bring the offering required for her, one-tenth of an ephah of barley meal; he shall pour no oil on it and put no frankincense on it, because it is a grain offering of jealousy, an offering for remembering, for bringing iniquity to remembrance.
