"So the king took his signet ring from his finger and gave it to Haman son of Hammedatha, the Agagite, the enemy of the Jews." NIV translation
The king agreed with Haman and gave him his ring. The ring would be used to put a mark on the decree so that everyone would know that it was done on the king's authority. Haman is once again described as an Agagite and "enemy of the Jews". We must remember that the Jews are God's chosen people and so it is logical that, if you are an enemy of the Jews, you are an enemy of God.
"'Keep the money,' the king said to Haman, 'and do with the people as you please.'" NIV translation
"Then on the thirteenth day of the first month the royal secretaries were summoned. They wrote out in the script of each province and in the language of each people all Haman's orders to the king's satraps, the governors of the various provinces and the nobles of the various peoples. These were written in the name of King Xerxes himself and sealed with his own ring." NIV translation
It is awesome how God is in charge of the smallest of details even when men think that they are in control. Here is another example as the secretaries were gathered to write the king's law for the destruction of God's people (the Jews). This happened on "the thirteenth day of the first month" which might not have meant anything to these pagans but is significant to God and His children. This is the day before the celebration of the Passover which occurs on the fourteenth day and is a feast of remembering the deliverance of God's people from Egypt. Just as God delivered His people from Egypt, He is already at work here in delivering His people from the hatred of Haman.
"Dispatches were sent by couriers to all the king's provinces with the order to destroy, kill and annihilate all the Jews - young and old, women and little children - on a single day, the thirteenth day of the twelfth month, the month of Adar, and to plunder their goods." NIV translation
Haman's plans are moving forward to kill all of the Jews as he is even telling them to kill the children.
The hate is deep rooted and is the same hate that was demonstrated by Hitler in World War Two and is coming out of the leadership of Iran today.
