לָכֵ֞ן כֹּֽה־אָמַ֣ר יְהוָ֗ה אִם־תָּשׁ֤וּב וַאֲשִֽׁיבְךָ֙ לְפָנַ֣י תַּֽעֲמֹ֔ד וְאִם־תּוֹצִ֥יא יָקָ֛ר מִזּוֹלֵ֖ל כְּפִ֣י תִֽהְיֶ֑ה יָשֻׁ֤בוּ הֵ֙מָּה֙ אֵלֶ֔יךָ וְאַתָּ֖ה לֹֽא־תָשׁ֥וּב אֲלֵיהֶֽם׃
因此永恆者如此說：你若回轉，我就使你復原，你必侍立在我面前；你若使寶貴的從卑賤的當中分別出來，你就如同我的口。他們必歸向你，你卻不可歸向他們。
Tosefta Horayot
The measure [allotted] to anyone that teaches a single chapter to his fellow, the verse ascribes to him as though he formed him, and shaped him, and brought him into this world, as it is said (Jer. 15:19), "If you bring out the precious (yakar) from what is worthless, you shall be as My spokesman (lit., 'My mouth')" (JPS Tr.). For just as the selfsame mouth [of God] imbued Adam the first man with a soul, so too [as to] anyone who brings a single creation under the wings of the shekhinah, we ascribe to him as though he formed him, and shaped him, and brought him into this world. And "precious" (yakarah) is Torah (lit., "teaching"), as it is said (Prov. 3:15), "She is more precious than rubies; [All of your goods cannot equal her]," and it says (Prov. 20:15), "Gold is plentiful, jewels abundant, But wise speech is a precious object" (JPS Tr.).
