Numbers 5:18Meaning & Commentary from the Church Fathers

In addition, the wife appears before the Judge without proper attire, lacking the adornment that is customary and fitting. The reason for this is clear: her shame reflects a moral failure and a charge of impurity. It is important to remember that a wife should not approach God unveiled, and Paul, knowledgeable in the law, cites the natural order as evidence that she ought to remain covered, stating that "her hair was given to her instead of a covering" (1 Cor. 11:15). Thus, the wife, accused of immodesty, stands without her usual dignified presentation.

Due to the jealousy provoked in her husband by her unrestrained and indulgent behavior, she is required to undergo purification. As her protector, it is the husband's duty to help cleanse her of her transgressions. "In the hand of the priest shall be the bitter water of reproof." This water was used by the priest to declare curses upon those who had sinned, hence it was referred to as the water of reproach.

He instructed that all these actions be taken, concerned that the woman might reconsider her ways if she had sinned, and that with genuine remorse she could find forgiveness. Thus, He ordered that she be presented before God with her head uncovered, illustrating that ‘all things are naked and unveiled before Him’ (Hebrews 4:13), and nothing we do escapes His sight. The intention behind God's command for the woman to conduct herself in this manner is clear from the subsequent verses (19-21).
