바이크라 (레위기) 20:26

ואבדל אתכם מן העמים להיות לי ‎ AND I HAVE SEPARATED YOU FROM THE PEOPLES THAT YOU SHOULD BE MINE — If you hold yourselves apart from them then you will be Mine, but if not, you belong to (become subject to) Nebuchadnezzar and others like him. Rabbi Eleazer ben Azariah said, “Whence do we know that one should not say, "My soul loathes swine’s flesh”, or, “I have no desire to wear clothes which are a mixture of wool and linen”, but one should say, "I would, indeed, like them, but what can I do since my Father in heaven has imposed these decrees upon me”? Because Scripture states: “I have separated you from the peoples to be for Me", whichyour separation from them (from their doings) should be for My sake — that one should keep aloof from sin and take upon himself the yoke of the kingdom of Heaven (Sifra, Kedoshim, Chapter 12 23).

וִהְיִ֤יתֶם לִי֙ קְדֹשִׁ֔ים כִּ֥י קָד֖וֹשׁ אֲנִ֣י יְהֹוָ֑ה וָאַבְדִּ֥ל אֶתְכֶ֛ם מִן־הָֽעַמִּ֖ים לִהְי֥וֹת לִֽי׃

And you shall be holy to me: for I the Lord am holy, and have separated you from the peoples, that you should be mine.
