Who is Queen…
She was the wife of Pharaoh, who gave her sister in marriage to Hadad, a royal Edomite (1 Kings 11:19—20)—an enemy of King Solomon raised up against him by God due to his great sins (1 Kings 11:1-22).
And Hadad found great favor in the sight of Pharaoh, so that he gave him in marriage the sister of his own wife, the sister of Tahpenes the queen. And the sister of Tahpenes bore him Genubath his son, whom Tahpenes weaned in Pharaoh's house. And Genubath was in Pharaoh's house among the sons of Pharaoh.
“Let me depart, that I may go to my own country.”
But Pharaoh said to him,
“What have you lacked with me that you are now seeking to go to your own country?”
And he said to him,
“Only let me depart.” —1 Kings 11:19-22 ESV
