Things turn out for the best - even for those who don't deserve it.

Now, after a hasty decision, we see Xerxes (Ahaseurus) regretting his action. His anger had taken a while to simmer down and he realised, because of the law he had been advised to make, that he could not take Vashti back. Did he love her? Was she a good queen? Did Xerxes rely on her, and miss her? She became queen again later, when her son succeeded Xerxes on his death; perhaps she was powerful and accomplished in her own right. Certainly it seems as if the advisers grasped the opportunity to get rid of her, so maybe she wielded power.

Whatever she was like, now he had no queen at all.

So his advisers suggested he choose another. Only the best, of course, so grab all the beautiful young girls to be found and then choose his favourite.
'This advice appealed to the king, and he followed it.'
You bet he did. Thinking, no doubt, that a young girl was much more likely to be acquiescent and do whatever he said - especially after the example that had been made of Vashti.

Ephesians 5: 15 says: So be careful how you live. Don't live like fools, but like those who are wise.

Good advice. Be careful. Think first.

As for Xerxes and his court: this is beginning to look like a soap opera...   Esther 2:1 - 4
