וְאַתֶּ֞ם תִּכְתְּב֤וּ אֶת־הָאָ֙רֶץ֙ שִׁבְעָ֣ה חֲלָקִ֔ים וַֽהֲבֵאתֶ֥ם אֵלַ֖י הֵ֑נָּה וְיָרִ֨יתִי לָכֶ֤ם גּוֹרָל֙ פֹּ֔ה לִפְנֵ֖י יְהוָ֥ה אֱלֹהֵֽינוּ׃
And ye shall describe the land into seven portions, and bring the description hither to me; and I will cast lots for you here before the LORD our God.
