Numbers 5:13-15

Revised Standard Version Catholic Edition

¹³ if a man lies with her carnally, and it is hidden from the eyes of her husband, and she is undetected though she has defiled herself, and there is no witness against her, since she was not taken in the act; ¹⁴ and if the spirit of jealousy comes upon him, and he is jealous of his wife who has defiled herself; or if the spirit of jealousy comes upon him, and he is jealous of his wife, though she has not defiled herself; ¹⁵ then the man shall bring his wife to the priest, and bring the offering required of her, a tenth of an ephah of barley meal; he shall pour no oil upon it and put no frankincense on it, for it is a cereal offering of jealousy, a cereal offering of remembrance, bringing iniquity to remembrance.
