בֵּ֛ן יְכַבֵּ֥ד אָ֖ב וְעֶ֣בֶד אֲדֹנָ֑יו וְאִם־אָ֣ב אָ֣נִי אַיֵּ֣ה כְבוֹדִ֡י וְאִם־אֲדוֹנִ֣ים אָנִי֩ אַיֵּ֨ה מוֹרָאִ֜י אָמַ֣ר ׀ יְהוָ֣ה צְבָא֗וֹת לָכֶם֙ הַכֹּֽהֲנִים֙ בּוֹזֵ֣י שְׁמִ֔י וַאֲמַרְתֶּ֕ם בַּמֶּ֥ה בָזִ֖ינוּ אֶת־שְׁמֶֽךָ׃
A son honoureth his father, And a servant his master; If then I be a father, Where is My honour? And if I be a master, Where is My fear? Saith the LORD of hosts Unto you, O priests, that despise My name. And ye say: ‘Wherein have we despised Thy name?’
Zohar
Rabbi Yeisa quoted the verse, "A son honors his father, and a servant his master" (Malachi 1:6). "A son" refers to Esau, for in the whole world there was no man who respected his father as Esau did; the homage he paid him made him ruler of the world.
