וַיְדַבֵּ֨ר אֵלַ֜י הָאִ֗ישׁ בֶּן־אָדָ֡ם רְאֵ֣ה בְעֵינֶיךָ֩ וּבְאָזְנֶ֨יךָ שְּׁמָ֜ע וְשִׂ֣ים לִבְּךָ֗ לְכֹ֤ל אֲשֶׁר־אֲנִי֙ מַרְאֶ֣ה אוֹתָ֔ךְ כִּ֛י לְמַ֥עַן הַרְאוֹתְכָ֖ה הֻבָ֣אתָה הֵ֑נָּה הַגֵּ֛ד אֶת־כָּל־אֲשֶׁר־אַתָּ֥ה רֹאֶ֖ה לְבֵ֥ית יִשְׂרָאֵֽל׃
그 사람이 내게 이르되 인자야 내가 네게 보이는 그것을 눈으로 보고 귀로 들으며 네 마음으로 생각할지어다 내가 이것을 네게 보이려고 이리로 데리고 왔나니 너는 본 것을 다 이스라엘 족속에게 고할지어다 하더라
Sifrei Devarim
(Devarim 32:46) "And he said to them: Put your hearts, etc.": We are hereby taught that one's eyes and heart and ears must be attuned to words of Torah. And thus is it written (Ezekiel 44:5) "And the L-rd said to me: Son of man, set your heart and see with your eyes, and hear with your ears all that I am saying to you about all the laws of the Temple … and set your heart to the entrance of the Temple and to all the exits of the sanctuary." Now does this not follow a fortiori? If re the Temple, which can be seen by the eyes and measured by the hand, one must "attune" his eyes and his heart and his ears — how much more so re words of Torah, which are like mountains hanging on a hair!
