The king's [Ahasuerus'] decision against the Jews was secured under false pretenses through misrepresentation of that peculiar people. Satan instigated the scheme in order to rid the earth of those who preserved the knowledge of the true God. But his plots were defeated by a counterpower that reigns among the children of men. Angels that excel in strength were commissioned to protect the people of God, and the plots of their adversaries returned upon their own heads.—Testimonies for the Church 5:450. TA 151.1
On the day appointed for their destruction, “the Jews gathered themselves together in their cities throughout all the provinces of the king Ahasuerus, to lay hand on such as sought their hurt: and no man could withstand them; for the fear of them fell upon all people.” Angels that excel in strength had been commissioned by God to protect His people while they “stood for their lives.” Esther 9:2, 16.—Prophets and Kings, 602. TA 151.2
