וְיִגְדַּ֨ל שִׁמְךָ֤ עַד־עוֹלָם֙ לֵאמֹ֔ר יְהוָ֣ה צְבָא֔וֹת אֱלֹהִ֖ים עַל־יִשְׂרָאֵ֑ל וּבֵית֙ עַבְדְּךָ֣ דָוִ֔ד יִהְיֶ֥ה נָכ֖וֹן לְפָנֶֽיךָ׃
願你的名永遠被尊為大，使人說：«萬軍的永恆者是治理以色列的上帝。»你僕人大衛的家也必在你面前堅立。
Mishneh Torah, Kings and Wars
The monarchy remains with the House of David forever, as it says, “your throne shall be established forever” (II Samuel 7:16). In contrast, if a king from (any of the other tribes of) Israel is appointed, the monarchy will cease from his House, as it says with regard to Jeraboam, “but not for all the days” (I Kings 11:39).
