וְעַתָּה֙ יְהוָ֣ה אֱלֹהִ֔ים הַדָּבָ֗ר אֲשֶׁ֨ר דִּבַּ֤רְתָּ עַֽל־עַבְדְּךָ֙ וְעַל־בֵּית֔וֹ הָקֵ֖ם עַד־עוֹלָ֑ם וַעֲשֵׂ֖ה כַּאֲשֶׁ֥ר דִּבַּֽרְתָּ׃
And now, O LORD God, the word that Thou hast spoken concerning Thy servant, and concerning his house, confirm Thou it for ever, and do as Thou hast spoken.
