Commentary for II Samuel 7:29

וְעַתָּ֗ה הוֹאֵל֙ וּבָרֵךְ֙ אֶת־בֵּ֣ית עַבְדְּךָ֔ לִהְי֥וֹת לְעוֹלָ֖ם לְפָנֶ֑יךָ כִּֽי־אַתָּ֞ה אֲדֹנָ֤י יְהוִה֙ דִּבַּ֔רְתָּ וּמִבִּרְכָ֣תְךָ֔ יְבֹרַ֥ךְ בֵּֽית־עַבְדְּךָ֖ לְעוֹלָֽם׃ (פ)

now therefore let it please Thee to bless the house of Thy servant, that it may continue for ever before Thee; for Thou, O Lord GOD, hast spoken it; and through Thy blessing let the house of Thy servant be blessed for ever.’
