וְעַתָּ֖ה מַמְלַכְתְּךָ֣ לֹא־תָק֑וּם בִּקֵּשׁ֩ יְהוָ֨ה ל֜וֹ אִ֣ישׁ כִּלְבָב֗וֹ וַיְצַוֵּ֨הוּ יְהוָ֤ה לְנָגִיד֙ עַל־עַמּ֔וֹ כִּ֚י לֹ֣א שָׁמַ֔רְתָּ אֵ֥ת אֲשֶֽׁר־צִוְּךָ֖ יְהוָֽה׃ (פ)
Ngunit ngayon, ang iyong paghahari ay hindi magpapatuloy. Humanap na ang Walang-Hanggan para sa Kanyang sarili ng isang lalaking ayon sa Kanyang puso, at itinalaga siya ng Walang-Hanggan bilang pinuno ng Kanyang bayan, sapagkat hindi mo sinunod ang iniutos sa iyo ng Walang-Hanggan.”
Rashi
But now, your kingship shall not endure. Because Moshe said so in the Torah, "[and] he does not stray from the commandment right or left, so that days of his reign are lengthy…."10 Devarim 17:20. Hence, if he does stray, the days [of his reign] will not be lengthy. And if you will argue that this was not said in reference to a Prophet's commandment, but only in reference to a commandment of the Torah, [I will answer that] it was already stated, "[and] to guard every word of this Torah" and afterwards, "that his pride not increase… and he turn not stray from the commandment"11Devarim 18:19. And now that you failed to obey the commandment of ‘ה to obey His word as delivered by His prophets, you will be held accountable for your actions. [to include] even a prophet's commandment.
