כִּֽי־שִׂפְתֵ֤י כֹהֵן֙ יִשְׁמְרוּ־דַ֔עַת וְתוֹרָ֖ה יְבַקְשׁ֣וּ מִפִּ֑יהוּ כִּ֛י מַלְאַ֥ךְ יְהוָֽה־צְבָא֖וֹת הֽוּא׃
대저 제사장의 입술은 지식을 지켜야 하겠고 사람들이 그 입에서 율법을 구하게 되어야 할 것이니 제사장은 만군의 여호와의 사자가 됨이어늘
Chagigah
But Rabbi Meir- how did he learn Torah from the mouth of Acher? But didn't Rabba the son of the son of Chana say, "Rabbi Yochanan said, 'What is [the meaning of] the verse, 'For my lips, a priest shall guard; knowledge and instruction they shall ask from his mouth, for he is an angel of Hashem of Legions (Malachi 2:7)'? If the teacher is like an angel of Hashem of Legions, they should ask instruction from his mouth; And if not, they should not ask instruction from his mouth.'"
