On the third day Esther put on her royal robes and stood in the inner court of the king’s palace, in front of the king’s quarters, while the king was sitting on his royal throne inside the throne room opposite the entrance to the palace.
Here is, I. Esther's bold approach to the king, Est 5:1. When the time appointed for their fast was finished she lost no time, but on the third day, when the impression of her devotions were fresh upon her spirit, she addressed the king. When the heart is enlarged in communion with God it will be emboldened in doing and suffering for him.
Commenting on Esther 5:1-8
Now it came to pass on the third day,.... Of the fast; though the former Targum paraphrases it the third day of the passover, the sixteenth of Nisan; see Gill on Est 4:17, though it is probable this was nearer the time fixed for the destruction of the Jews, see Est 8:9, yet the Jews have fixed the fast of Esther on that very day...
Now it came to pass on the third day, that Esther put on [her] royal [apparel], and stood in the inner court of the king's house, over against the king's house: and the king sat upon his royal throne in the royal house, over against the gate of the house. (a) That is, after the Jews had begun to fast.
