Numbers 5:17-19 Common English Bible (CEB)
17 The priest will take holy water in a clay jar, and taking dust from the floor of the dwelling, the priest will place it in the water. 18 The priest will make the woman stand before the Lord, let the hair of the woman hang down, and place the grain offering for recognition, that is, the grain offering for jealousy, in her hands. The water of bitterness that brings the curse will be in the hands of the priest.
19 Then the priest will make her swear a solemn pledge, saying to the woman, “If no man has slept with you and if you haven’t had an affair, becoming defiled while married to your husband, then be immune from the water of bitterness that brings these curses.
