וַיֹּ֧אמֶר מָנ֛וֹחַ אֶל־אִשְׁתּ֖וֹ מ֣וֹת נָמ֑וּת כִּ֥י אֱלֹהִ֖ים רָאִֽינוּ׃
瑪挪亞對他的妻子說：«我們必定要死，因為我們看見了上帝的天使。»
Netivot Olam
...If one studies Torah only for oneself, then they set a limit upon what they might uncover, alone. And this is a shame, since the attribute of lovingkindness (ḥesed) in Torah is without limit. Therefore, study Torah in order to teach others in order for the study to attach itself to ḥesed.
