וְלִבְנ֖וֹ אֶתֵּ֣ן שֵֽׁבֶט־אֶחָ֑ד לְמַ֣עַן הֱיֽוֹת־נִ֣יר לְדָֽוִיד־עַ֠בְדִּי כָּֽל־הַיָּמִ֤ים ׀ לְפָנַי֙ בִּיר֣וּשָׁלִַ֔ם הָעִיר֙ אֲשֶׁ֣ר בָּחַ֣רְתִּי לִ֔י לָשׂ֥וּם שְׁמִ֖י שָֽׁם׃
我要把一個支派賜給他的兒子，使我僕人大衛在耶路撒冷，在我面前，永遠保有王權；耶路撒冷是我為自己揀選、要在那裡立我名的城。
Rashi
A lamp. A kingdom. ניר is an expression of a yoke.13The king’s subjects must obey their king, just as the ox must obey the person controlling his yoke. Alternatively, ניר means “a candle [=נר],” just as a candle illuminates its surroundings, so does a king influence his subjects.—Metzudas Dovid
