Commentary for II Kings 9:17

וְהַצֹּפֶה֩ עֹמֵ֨ד עַֽל־הַמִּגְדָּ֜ל בְּיִזְרְעֶ֗אל וַיַּ֞רְא אֶת־שִׁפְעַ֤ת יֵהוּא֙ בְּבֹא֔וֹ וַיֹּ֕אמֶר שִׁפְעַ֖ת אֲנִ֣י רֹאֶ֑ה וַיֹּ֣אמֶר יְהוֹרָ֗ם קַ֥ח רַכָּ֛ב וּֽשְׁלַ֥ח לִקְרָאתָ֖ם וְיֹאמַ֥ר הֲשָׁלֽוֹם׃

Now the watchman stood on the tower in Jezreel, and he spied the company of Jehu as he came, and said: ‘I see a company.’ And Joram said: ‘Take a horseman, and send to meet them, and let him say: Is it peace?’
