John Gill Commentary Esther 5:4

"And Esther said, If it seem good unto the king, let the king and Haman come this day unto the banquet that I have prepared for him." — Esther 5:4 (ASV)

And Esther answered, if it seem good unto the king

She humbly submits it to his pleasure, suggesting it would be exceeding grateful to her, could it be granted:

let the king and Haman come this day unto the banquet that I have prepared for him ;

for the king; and supposing it would be acceptable to him, and the rather engage him to come to it, she invited his favourite; and chiefly, that she might have an opportunity of accusing him before the king to his face, and when alone.
