שׂ֣וֹם תָּשִׂ֤ים עָלֶ֙יךָ֙ מֶ֔לֶךְ אֲשֶׁ֥ר יִבְחַ֛ר יְהוָ֥ה אֱלֹהֶ֖יךָ בּ֑וֹ מִקֶּ֣רֶב אַחֶ֗יךָ תָּשִׂ֤ים עָלֶ֙יךָ֙ מֶ֔לֶךְ לֹ֣א תוּכַ֗ל לָתֵ֤ת עָלֶ֙יךָ֙ אִ֣ישׁ נָכְרִ֔י אֲשֶׁ֥ר לֹֽא־אָחִ֖יךָ הֽוּא׃
thou shalt in any wise set him king over thee, whom the LORD thy God shall choose; one from among thy brethren shalt thou set king over thee; thou mayest not put a foreigner over thee, who is not thy brother.
Pirkei Avot
Rabbi Judah said: be careful in study, for an error in study counts as deliberate sin. Rabbi Shimon said: There are three crowns: the crown of torah, the crown of priesthood, and the crown of royalty, but the crown of a good name supersedes them all.
