וְעַתָּ֖ה מַמְלַכְתְּךָ֣ לֹא־תָק֑וּם בִּקֵּשׁ֩ יְהוָ֨ה ל֜וֹ אִ֣ישׁ כִּלְבָב֗וֹ וַיְצַוֵּ֨הוּ יְהוָ֤ה לְנָגִיד֙ עַל־עַמּ֔וֹ כִּ֚י לֹ֣א שָׁמַ֔רְתָּ אֵ֥ת אֲשֶֽׁר־צִוְּךָ֖ יְהוָֽה׃ (פ)
But now thy kingdom shall not continue; the LORD hath sought him a man after His own heart, and the LORD hath appointed him to be prince over His people, because thou hast not kept that which the LORD commanded thee.’
