Numbers 5:14

11 And Jehovah spake unto Moses, saying,

12 Speak unto the children of Israel, and say unto them, If any man`s wife go aside, and commit a trespass against him,

13 and 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;

14 and 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:

15 then 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.

16 And the priest shall bring her near, and set her before Jehovah:

17 and the priest shall take holy water in an earthen vessel; and of the dust that is on the floor of the tabernacle the priest shall take, and put it into the water.
