Just one example of how not a single word was left unexplored by our Rabbis [Chachamim]

11And they shall be prepared for the third day, for on the third day, the Lord will descend before the eyes of all the people upon Mount Sinai. יאוְהָי֥וּ נְכֹנִ֖ים לַיּ֣וֹם הַשְּׁלִישִׁ֑י כִּ֣י | בַּיּ֣וֹם הַשְּׁלִשִׁ֗י יֵרֵ֧ד יְהוָֹ֛ה לְעֵינֵ֥י כָל־הָעָ֖ם עַל־הַ֥ר סִינָֽי:

Rashi: [the “Master” explainer of Tora verses]

before the eyes of all the people: [This] teaches [us] that there were no blind [persons] among them, for they were all cured. — [from Mechilta]לעיני כל העם: מלמד שלא היה בהם סומא, שנתרפאו כולם
