וְהַנָּשִׂ֨יא אֲשֶׁר־בְּתוֹכָ֜ם אֶל־כָּתֵ֤ף יִשָּׂא֙ בָּעֲלָטָ֣ה וְיֵצֵ֔א בַּקִּ֥יר יַחְתְּר֖וּ לְה֣וֹצִיא ב֑וֹ פָּנָ֣יו יְכַסֶּ֔ה יַ֗עַן אֲשֶׁ֨ר לֹא־יִרְאֶ֥ה לַעַ֛יִן ה֖וּא אֶת־הָאָֽרֶץ׃
And the prince that is among them shall bear upon his shoulder, and go forth in the darkness; they shall dig through the wall to carry out thereby; he shall cover his face, that he see not the ground with his eyes.
