Finally, the goodness of God manifests itself in the preservation of His people Israel. It could not have survived the enmity of the Gentiles, if God had not appointed protectors for it, the archangels Michael and Gabriel. Whenever Israel disobeys God, and is accused of misdemeanors by the angels of the other nations, he is defended by his designated guardians, with such good result that the other angels conceive fear of them. Once the angels of the other nations are terrified, the nations themselves venture not to carry out their wicked designs against Israel.
