Esther 5:12
“Haman said moreover, Yea, Esther the queen did let no man come in with the king unto the banquet that she had prepared but myself; and to morrow am I invited unto her also with the king.”
KJV
Read in Esther 5Meaning
Haman interprets Esther's exclusive invitation as further proof of his importance. The reader knows more than he does, so his boasting becomes dramatic irony: the honor he celebrates is bringing him closer to exposure.
