Esther 7:7 And the king arose in his wrath from the wine-drinking and went into the palace garden, but Haman stayed to beg for his life from Queen Esther, for he saw that harm was determined against him by the king.
After Queen Esther exposed Haman of his wicked plot, the king became furious and, in his wrath, stormed out of the area in which they were feasting and went into the palace garden – likely to think. Yes, this was a pagan king with a temper and Haman deserved to be executed for his crimes, but King Ahasuerus did a noble thing by taking a moment to cool off and think about the gravity of the situation. Again, remember that they had all been drinking up to this point and it is probably safe to assume that the king had learned over the years not to cast life-altering judgments too quickly, especially while intoxicated (cf. 1:10-22). That being said, do keep in mind that it is possible he simply left to fetch the guards.
It is interesting to note that, up until this moment, the Israelites were under the condemnation of this man, but now the tables had turned. Haman was officially at the mercy of this Jewish queen. Thus, while the king was out in the garden, Haman pleaded with Queen Esther to save his life from death because he had most likely seen that look of wrath in the king’s eyes before. After all, Haman was the king’s right-hand man (3:1), so he would have known him all too well. Not only that, but he would have also realized that it never goes well when you mess with another man’s wife.
