וַיָּב֥וֹא יֵה֖וּא יִזְרְעֶ֑אלָה וְאִיזֶ֣בֶל שָׁמְעָ֗ה וַתָּ֨שֶׂם בַּפּ֤וּךְ עֵינֶ֙יהָ֙ וַתֵּ֣יטֶב אֶת־רֹאשָׁ֔הּ וַתַּשְׁקֵ֖ף בְּעַ֥ד הַחַלּֽוֹן׃
耶戶來到耶斯列。耶洗別聽見了，就用黛墨畫眼，梳妝頭髮，從窗戶往外觀看。
Rashi
And made up her hair. [Targum Yonoson] (renders) וּתְקָנַת יַת רֵישָׁהּ [=she adorned her head], in order to have charm in Yeihu’s eyes and he would marry her.28Alternatively, she made herself look beautiful hoping that Yeihu would spare her life.—Metzudas Dovid
