אֲשֶׁר־יֵצֵ֣א לִפְנֵיהֶ֗ם וַאֲשֶׁ֤ר יָבֹא֙ לִפְנֵיהֶ֔ם וַאֲשֶׁ֥ר יוֹצִיאֵ֖ם וַאֲשֶׁ֣ר יְבִיאֵ֑ם וְלֹ֤א תִהְיֶה֙ עֲדַ֣ת יְהוָ֔ה כַּצֹּ֕אן אֲשֶׁ֥ר אֵין־לָהֶ֖ם רֹעֶֽה׃
who may go out before them, and who may come in before them, and who may lead them out, and who may bring them in; that the congregation of the LORD be not as sheep which have no shepherd.’
