Esther 9

Here's what bothers me about the book of Esther. First, these were Jews who didn't return to the Promised Land. Second, as far as we know their plans were made entirely independent of God. As an example, Queen Esther's marriage was forbidden under the law. Third, the killings in this chapter were revenge, and that's something God reserved for himself.

I'm not saying Esther doesn't belong in the Bible. I'm saying that I don't understand.
