Numbers 5:15-17

American Standard Version

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.
