The Star of Christmas (Numbers 24:10-25)

Balak has been paying Balaam to manipulate and to change the promises of the Lord.  They have offered the Lord the highest and greatest offerings to win the favor of God.  The Lord has responded to the sacrifices, but not in the way that Balak had hoped.  The Lord has continued to restate His promises to this man.  Now, in this fourth oracle something that changed.  There are no sacrifices, but the Lord reminds these men, and us today that his battle plan is fixed.  What is the significance of this oracle?  What does this tell us about the Christmas story?
