Num 33:54

וְהִתְנַחַלְתֶּם֩ אֶת־הָאָ֨רֶץ בְּגוֹרָ֜ל לְמִשְׁפְּחֹֽתֵיכֶ֗ם לָרַ֞ב תַּרְבּ֤וּ אֶת־נַחֲלָתוֹ֙ וְלַמְעַט֙ תַּמְעִ֣יט אֶת־נַחֲלָת֔וֹ אֶל֩ אֲשֶׁר־יֵ֨צֵא ל֥וֹ שָׁ֛מָּה הַגּוֹרָ֖ל ל֣וֹ יִהְיֶ֑ה לְמַטּ֥וֹת אֲבֹתֵיכֶ֖ם תִּתְנֶחָֽלוּ׃

And you are to divide the land by lot according to your clans. Give a larger inheritance to a larger clan and a smaller inheritance to a smaller one. Whatever falls to each one by lot will be his. You will receive an inheritance according to the tribes of your fathers.
