Numbers 5:17 WBT

¹⁵  Then shall the man bring his wife to the priest, and he shall bring her offering for her, the tenth [part] of an ephah of barley-meal; he shall pour no oil upon it, nor put frankincense upon it; for it [is] an offering of jealousy, an offering of memorial, bringing iniquity to remembrance.

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

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:

¹⁸  And the priest shall set the woman before the LORD, and uncover the woman's head, and put the offering of memorial in her hands, which [is] the jealousy-offering: and the priest shall have in his hand the bitter water that causeth the curse:

¹⁹  And the priest shall charge her by an oath, and say to the woman, If no man hath lain with thee, and if thou hast not gone aside to uncleanness [with another] instead of thy husband, be thou free from this bitter water that causeth the curse:
