כֵּ֣ן יִֽהְיֶ֤ה דְבָרִי֙ אֲשֶׁ֣ר יֵצֵ֣א מִפִּ֔י לֹֽא־יָשׁ֥וּב אֵלַ֖י רֵיקָ֑ם כִּ֤י אִם־עָשָׂה֙ אֶת־אֲשֶׁ֣ר חָפַ֔צְתִּי וְהִצְלִ֖יחַ אֲשֶׁ֥ר שְׁלַחְתִּֽיו׃
So shall My word be that goeth forth out of My mouth: It shall not return unto Me void, Except it accomplish that which I please, And make the thing whereto I sent it prosper.
