Elijah hastened to Mordecai, who, when first he heard what God had resolved upon, tore his garments and was possessed by a great fear, though before he had confidently hoped that help would come form God. He gathered together all the school children, and had them fast, so that their hunger should drive them to moan and groan. Then it was that Israel spoke to God: "O Lord of the world! When the heathen rage against me, they do not desire my silver and gold, they desire only that I should be exterminated from off the face of the earth. Such was the design of Nebuchadnezzar when he wanted to compel Israel to worship the idol. Had it not been for Hananiah, Mishael, and Azariah, I had disappeared from the world. Now it is Haman who desires to uproot the whole vine."
