Commentary for I Kings 14:5

וַיהוָ֞ה אָמַ֣ר אֶל־אֲחִיָּ֗הוּ הִנֵּ֣ה אֵ֣שֶׁת יָרָבְעָ֡ם בָּאָ֣ה לִדְרֹשׁ֩ דָּבָ֨ר מֵעִמְּךָ֤ אֶל־בְּנָהּ֙ כִּֽי־חֹלֶ֣ה ה֔וּא כָּזֹ֥ה וְכָזֶ֖ה תְּדַבֵּ֣ר אֵלֶ֑יהָ וִיהִ֣י כְבֹאָ֔הּ וְהִ֖יא מִתְנַכֵּרָֽה׃

Now the LORD had said unto Ahijah: ‘Behold, the wife of Jeroboam cometh to inquire of thee concerning her son; for he is sick; thus and thus shalt thou say unto her; for it will be, when she cometh in, that she will feign herself to be another woman.’
