Numbers 5:11-19

11And the LORD 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, neither she be 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.

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

17and 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:

18and the priest shall set the woman before the LORD, and let the hair of the woman’s head go loose, and put the meal offering of memorial in her hands, which is the meal offering of jealousy: and the priest shall have in his hand the water of bitterness that causeth the curse:

19and the priest shall cause her to swear, and shall say unto the woman, If no man have lain with thee, and if thou hast not gone aside to uncleanness, being under thy husband, be thou free from this water of bitterness that causeth the curse:
