בֵּ֣ית דָּוִ֗ד כֹּ֚ה אָמַ֣ר יְהוָ֔ה דִּ֤ינוּ לַבֹּ֙קֶר֙ מִשְׁפָּ֔ט וְהַצִּ֥ילוּ גָז֖וּל מִיַּ֣ד עוֹשֵׁ֑ק פֶּן־תֵּצֵ֨א כָאֵ֜שׁ חֲמָתִ֗י וּבָעֲרָה֙ וְאֵ֣ין מְכַבֶּ֔ה מִפְּנֵ֖י רֹ֥עַ מעלליהם [מַעַלְלֵיכֶֽם׃]
Maison de David, ainsi parle l’Éternel: "Rendez bonne justice dès la première heure, sauvez celui qui a été spolié de la main de l’oppresseur: sans cela, ma colère éclatera comme un incendie et brûlera inextinguible, à cause de la perversité de vos œuvres."
Mishnah Sanhedrin
The king can neither judge nor be judged, he cannot testify and others cannot testify against him. He may not perform halitzah, nor may others perform halitzah for his wife. He may not contract levirate marriage nor may his brothers contract levirate marriage with his wife. Rabbi Judah says: “If he wished to perform halitzah or to contract levirate marriage his memory is a blessing.” They said to him: “They should not listen to him.” None may marry his widow. Rabbi Judah says: “The king may marry the widow of a king, for so have we found it with David, who married the widow of Saul, as it says, “And I gave you my master’s house and my master’s wives into your embrace” (II Samuel 12:8).
