Commentary for I Kings 18:10

חַ֣י ׀ יְהוָ֣ה אֱלֹהֶ֗יךָ אִם־יֶשׁ־גּ֤וֹי וּמַמְלָכָה֙ אֲ֠שֶׁר לֹֽא־שָׁלַ֨ח אֲדֹנִ֥י שָׁם֙ לְבַקֶּשְׁךָ֔ וְאָמְר֖וּ אָ֑יִן וְהִשְׁבִּ֤יעַ אֶת־הַמַּמְלָכָה֙ וְאֶת־הַגּ֔וֹי כִּ֖י לֹ֥א יִמְצָאֶֽכָּה׃

As the LORD thy God liveth, there is no nation or kingdom, whither my lord hath not sent to seek thee; and when they said: He is not here, he took an oath of the kingdom and nation, that they found thee not.
