לא מרבכם. כִּפְשׁוּטוֹ; וּמִדְרָשׁוֹ לְפִי שֶׁאֵין אַתֶּם מַגְדִּילִים עַצְמְכֶם כְּשֶׁאֲנִי מַשְׁפִּיעַ לָכֶם טוֹבָה, לְפִיכָךְ חשק … בכם לא מרבכם NOT ON ACCOUNT OF YOUR BEING [MORE] NUMEROUS — This is to he understood according to its plain sense. But its Midrashic explanation (taking לא מרבכם in the sense of “not because you are great") is: Because you do not regard yourselves as great when I shower good, upon you, therefore חשק … בכם DID [THE LORD] DELIGHT IN YOU
כי אתם המעט – הַמְמַעֲטִין עַצְמְכֶם, כְּגוֹן אַבְרָהָם שֶׁאָמַר (בראשית י"ח) "וְאָנֹכִי עָפָר וָאֵפֶר", וּכְגוֹן מֹשֶׁה וְאַהֲרֹן שֶׁאָמְרוּ (שמות ט"ז) "וְנַחְנוּ מָה", לֹא כִנְבוּכַדְנֶאצַּר שֶׁאָמַר (ישעיהו י"ד) "אֶדַּמֶּה לְעֶלְיוֹן", וְסַנְחֵרִיב (שם ל"ו) שֶׁאָמַר "מִי בְּכָל אֱלֹהֵי הָאֲרָצוֹת", וְחִירָם שֶׁאָמַר (י"ח כ"ח) "אֵל אָנִי מוֹשַׁב אֱלֹהִים יָשַׁבְתִּי" (חולין פ"ט): כי אתם המעט FOR YOU ARE LITTLE — you regard yourselves as small, as, e.g., Abraham did who said, (Genesis 18:27) “For I am dust and ashes", and as, e.g., Moses and Aaron did who said, (Exodus 16:7) “And we, what are we?". Not as Nebuchadnezzar who said, (Isaiah 14:14) “I will be like the Most High", and Sennacherib who said, (Isaiah 36:20) “Who are they among all the gods of these countries [that have delivered their countries out of my hand?]", and Hiram who said, (Er. 28:2), “I am a god, I sit in the seat of God" (Chullin 89a).
כי אתם המעט. הֲרֵי כִּי מְשַׁמֵּשׁ בִּלְשׁוֹן דְּהָא: כי אתם המעט — Here you have the word כי used in the sense of “because".
