Esther 1:12
“But the queen Vashti refused to come at the king’s commandment by his chamberlains: therefore was the king very wroth, and his anger burned in him.”
KJV
Read in Esther 1Meaning
The narrative does not state Vashti's reason, so interpretation should not invent one. What the text emphasizes is the collision between her refusal and the king's expectation of obedience, which abruptly transforms a lavish feast into a political problem.
