The spirit of jealousy, &c. This ordinance was designed to clear the innocent, and to prevent jealous husbands from doing mischief to their wives: as likewise to give all a horror of adultery, by punishing it in so remarkable a manner. (Challoner)

The spirit of jealousy, of fear, &c., denotes those passions of the soul. This very remarkable law of Moses suited the genius of his people, (Calmet) and tended greatly to restrain the infidelity of the married couple, and the fury of suspicious husbands. (Theodoret, q. 10.) God was pleased, by a continual miracle, to manifest the truth, on this occasion, provided the husband were not also guilty: for, in that case, the Rabbins assert, the waters had no effect. They relate many particularities, which seem contrary to Philo and Josephus, who inform us that the trial was still made in their time, though the former writers pretend that it was disused, on account of the many adulteries which were committed, in the age preceding the destruction of the temple by Titus. They say that the person who had committed the crime with the woman, died at the same time that the bitter waters put an end to her existence. When the suspected person was brought before the Sanhedrim, they tried, by all means, to extort a confession from her. But if she persisted in maintaining her innocence, they made her stand in black, before the eastern gate of the court, denouncing to her what she had to expect. If she answered Amen, the priest wrote the imprecations (ver. 19-22,) on vellum, with ink, which had no mixture of vitriol in it; and taking water from the laver, and dust from the court, with something bitter, like wormwood, effaced the writing in a new earthen vessel; while another priest tore her garments as far as the breast, and tied them up with an Egyptian cord, to remind her of the miracles wrought by God. If she confessed the crime before the writing was effaced, she was to be repudiated, without any dowry; or, if she kept company with a suspected person, contrary to her husband’s admonition, after she had come off victorious from drinking the bitter waters, she was subjected to the same punishment, and could not demand to be admitted any more to make the miraculous experiment.
