Numbers 5:15-17 World English Bible (WEB)

15. then the man shall bring his wife to the priest, and shall bring her offering for her: one tenth of an ephah of barley meal. He shall pour no oil on it, nor put frankincense on it, for it is a meal offering of jealousy, a meal offering of memorial, bringing iniquity to memory.

16. The priest shall bring her near, and set her before Yahweh;

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.
