Deuteronomy – The Laws of the King
Deuteronomy 17:14-20
The Torah prescribes the laws governing the appointment of a king: he must be chosen by God, must not accumulate excessive horses, wives, or wealth, and must write and read from the Torah all his days so that he does not exalt himself above his people.
שׂ֣וֹם תָּשִׂ֤ים עָלֶ֙יךָ֙ מֶ֔לֶךְ אֲשֶׁ֥ר יִבְחַ֛ר יְהֹוָ֥ה אֱלֹהֶ֖יךָ בּ֑וֹ מִקֶּ֣רֶב אַחֶ֗יךָ תָּשִׂ֤ים עָלֶ֙יךָ֙ מֶ֔לֶךְ לֹ֣א תוּכַ֗ל לָתֵ֤ת עָלֶ֙יךָ֙ אִ֣ישׁ נׇכְרִ֔י אֲשֶׁ֥ר לֹֽא־אָחִ֖יךָ הֽוּא׃ וְהָיָ֣ה כְשִׁבְתּ֔וֹ עַ֖ל כִּסֵּ֣א מַמְלַכְתּ֑וֹ וְכָ֨תַב ל֜וֹ אֶת־מִשְׁנֵ֨ה הַתּוֹרָ֤ה הַזֹּאת֙ עַל־סֵ֔פֶר מִלִּפְנֵ֖י הַכֹּהֲנִ֥ים הַלְוִיִּֽם׃ וְהָיְתָ֣ה עִמּ֔וֹ וְקָ֥רָא ב֖וֹ כׇּל־יְמֵ֣י חַיָּ֑יו לְמַ֣עַן יִלְמַ֗ד לְיִרְאָה֙ אֶת־יְהֹוָ֣ה אֱלֹהָ֔יו לִ֠שְׁמֹ֠ר אֶֽת־כׇּל־דִּבְרֵ֞י הַתּוֹרָ֥ה הַזֹּ֛את וְאֶת־הַחֻקִּ֥ים הָאֵ֖לֶּה לַעֲשֹׂתָֽם׃ לְבִלְתִּ֤י רוּם־לְבָבוֹ֙ מֵֽאֶחָ֔יו וּלְבִלְתִּ֛י ס֥וּר מִן־הַמִּצְוָ֖ה יָמִ֣ין וּשְׂמֹ֑אול לְמַ֩עַן֩ יַאֲרִ֨יךְ יָמִ֧ים עַל־מַמְלַכְתּ֛וֹ ה֥וּא וּבָנָ֖יו בְּקֶ֥רֶב יִשְׂרָאֵֽל׃ {ס}
you shall be free to set a king over yourself, one chosen by the ETERNAL your God. Be sure to set as king over yourself one of your own people; you must not set a foreigner over you, one who is not your fellow Israelite. When he is seated on his royal throne, he shall have a copy of this Teaching written for him on a scroll by the levitical priests. Let it remain with him and let him read in it all his life, so that he may learn to revere the ETERNAL his God, to observe faithfully every word of this Teaching as well as these laws. Thus he will not act haughtily toward his fellows or deviate from the Instruction to the right or to the left, to the end that he and his descendants may reign long in the midst of Israel.
Why it matters — The foundational biblical text on leadership sets limits on power and demands that the leader remain humble and Torah-bound — defining leadership as service under divine authority.
