Numbers 5:12 - Wesley's Explanatory Notes

If a man's wife — This law was given partly to deter wives from adulterous practices, and partly to secure wives against the rage of their hard — hearted husbands, who otherwise might upon mere suspicions destroy them, or at least put them away. There was not like fear of inconveniences to the husband from the jealousy, of the wife, who had not that authority and power, and opportunity for the putting away or killing the husband, as the husband had over the wife. Go aside — From the way of religion and justice, and that either in truth, or in her husband's opinion.
