The law of the bitter waters for wives suspected of adultery; God alone can reveal hidden sins; the wife's innocence or guilt is manifested by a miraculous divine judgment.

If the woman is not defiled, she shall be free and shall conceive children; the ordeal vindicates the innocent. God is the supreme judge of secret sins.
