Commentary for I Kings 11:19

וַיִּמְצָא֙ הֲדַ֥ד חֵ֛ן בְּעֵינֵ֥י פַרְעֹ֖ה מְאֹ֑ד וַיִּתֶּן־ל֤וֹ אִשָּׁה֙ אֶת־אֲח֣וֹת אִשְׁתּ֔וֹ אֲח֖וֹת תַּחְפְּנֵ֥יס הַגְּבִירָֽה׃

And Hadad found great favour in the sight of Pharaoh, so that he gave him to wife the sister of his own wife, the sister of Tahpenes the queen.
