John Gill Commentary Esther 6:5

"And the king`s servants said unto him, Behold, Haman standeth in the court. And the king said, Let him come in." — Esther 6:5 (ASV)

And the king's servants said to him, behold, Haman stands
in the court
In the outward court; for into the inward court none might enter without being called, for which he was waiting:

and the king said, let him come in ;
into his bedchamber; and it was of God, no doubt, that Haman should be on the spot at this very time, when the king was in the humour to do honour to Mordecai, and by him.
