וַהֲקִ֣ימוֹתִ֔י אֵ֖ת כִּסֵּ֣א מַלְכוּתֶ֑ךָ כַּאֲשֶׁ֣ר כָּרַ֗תִּי לְדָוִ֤יד אָבִ֙יךָ֙ לֵאמֹ֔ר לֹֽא־יִכָּרֵ֤ת לְךָ֙ אִ֔ישׁ מוֹשֵׁ֖ל בְּיִשְׂרָאֵֽל׃

then I will establish the throne of thy kingdom, according as I covenanted with David thy father, saying: There shall not fail thee a man to be ruler in Israel.
