וְלִבְנ֖וֹ אֶתֵּ֣ן שֵֽׁבֶט־אֶחָ֑ד לְמַ֣עַן הֱיֽוֹת־נִ֣יר לְדָֽוִיד־עַ֠בְדִּי כָּֽל־הַיָּמִ֤ים ׀ לְפָנַי֙ בִּיר֣וּשָׁלִַ֔ם הָעִיר֙ אֲשֶׁ֣ר בָּחַ֣רְתִּי לִ֔י לָשׂ֥וּם שְׁמִ֖י שָֽׁם׃
At sa kanyang anak ay ibibigay ko ang isang lipi, upang si David na aking lingkod ay laging magkaroon ng paghahari sa harap ko sa Jerusalem, ang lungsod na aking pinili para sa akin upang ilagay roon ang aking pangalan.
Mishneh Torah, Kings and Wars
Should a prophet install a king from any of the other Tribes of Israel, and that king follows in the ways of the Torah and observes the Commandments, and fights the Wars of G-d, he, too, is a king and all the Commandments of the King are applicable to him. This, even though the “essential” monarchy belongs to David and from his children there will be kings. For we see that Achiya the Shilonite appointed Jeraboam and said to him, “And it will be, if you listen to all that I command you…and I shall build for you a sure house as I built for David…” (I Kings 11:38). And Achiya said to him, “And to his son, I shall give one tribe, so that it shall be a remembrance for David my servant for all days before me in Jerusalem” (I Kings 11:39).
