בָּעֵ֣ת הַהִ֗וא הִבְדִּ֤יל יְהוָה֙ אֶת־שֵׁ֣בֶט הַלֵּוִ֔י לָשֵׂ֖את אֶת־אֲר֣וֹן בְּרִית־יְהוָ֑ה לַעֲמֹד֩ לִפְנֵ֨י יְהוָ֤ה לְשָֽׁרְתוֹ֙ וּלְבָרֵ֣ךְ בִּשְׁמ֔וֹ עַ֖ד הַיּ֥וֹם הַזֶּֽה׃
Naquele tempo, Yehovah separou a tribo de Levi para carregar a Arca da Aliança de Yehovah, para estar diante de Yehovah para servi-Lo e abençoar em Seu Nome, até este dia.
Mishnah Horayot
A priest takes precedence over a levite, a levite over an israelite, an israelite over a mamzer, a mamzer over a natin, a natin over a convert, and a convert over a freed slave. When is this so? When all these were in other respects equal. However, if the mamzer was a scholar and the high priest an ignoramus, the scholar mamzer takes precedence over the ignorant high priest.
