V.1-6 Haman is raised to great power by Ahasuerus. He takes great pleasure in seeing everyone bow down to him but Mordecai the Jew will not bow. Although God’s name is not mentioned in this book of Esther, we can see that God’s Word was known and obeyed. The ten commandments (Ex. 20:55Thou shalt not bow down thyself to them, nor serve them: for I the Lord thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me; (Exodus 20:5)) were being followed here, cost what they may. The believer obeys the laws of his land. But when those laws come into conflict with what the Word of God says, then he obeys the Word.
V.7-15 Haman is so angry about this, that instead of trying to get rid of Mordecai, he decides to get rid of all the Jews in the whole kingdom.
V.8 Interesting verse. Modern writers today claim that the Bible is just made up from the writings of other peoples. Notice what this verse says which utterly denies this.
V.15 Just like the world today. It sits down to drink, but it does not know what is ahead. Haman thought that he was in control but wait!
