וַאֲנַ֜חְנוּ נֵחָלֵ֣ץ חֻשִׁ֗ים לִפְנֵי֙ בְּנֵ֣י יִשְׂרָאֵ֔ל עַ֛ד אֲשֶׁ֥ר אִם־הֲבִֽיאֹנֻ֖ם אֶל־מְקוֹמָ֑ם וְיָשַׁ֤ב טַפֵּ֙נוּ֙ בְּעָרֵ֣י הַמִּבְצָ֔ר מִפְּנֵ֖י יֹשְׁבֵ֥י הָאָֽרֶץ׃
but we ourselves will be ready armed to go before the children of Israel, until we have brought them unto their place; and our little ones shall dwell in the fortified cities because of the inhabitants of the land.
