Esther 5:4 - Joseph Benson’s Commentary on the Old and New Testaments

Let the king and Haman come this day unto the banquet She thought it prudent not to open her mind to him immediately, but first to try how he stood affected to her, and endeavour to endear herself more to him, that he might be the better disposed to grant her request. To accomplish which purpose still more effectually, she desired to entertain him at her banquet a second time, Esther 5:8. And she, each time, invited Haman, that by showing such respect to the king's great favourite she might insinuate herself the more into the king's affection; and that, if she saw fit, she might then present her request to the king.
