אמר רב יהודה אמר רב:
אדם הראשון מין היה
שנאמר (בראשית ג, ט) וַיִּקְרָ֛א יְהֹוָ֥ה אֱלֹהִ֖ים אֶל־הָֽאָדָ֑ם וַיֹּ֥אמֶר ל֖וֹ אַיֶּֽכָּה -
אן נטה לבך.
...
רב נחמן אמר: כופר בעיקר היה -
כתיב הכא וְהֵ֕מָּה כְּאָדָ֖ם עָבְר֣וּ בְרִ֑ית (הושע ו ז)
וכתיב התם אֶת־בְּרִיתִ֖י הֵפַֽר (בראשית י״ז:יד)
(ירמיהו כב, ט) וְאָ֣מְר֔וּ עַ֚ל אֲשֶׁ֣ר עָזְב֔וּ אֶת־בְּרִ֥ית יְהֹוָ֖ה אֱלֹהֵיהֶ֑ם וַיִּֽשְׁתַּחֲו֛וּ לֵאלֹהִ֥ים אֲחֵרִ֖ים וַיַּעַבְדֽוּם.
Rav Yehuda says that Rav says:
Adam the first man was a MIN,
as it is stated: “And the Lord called to the man and said to him: Where are you”? (Genesis 3:9), meaning, to where has your heart turned?
...
Rav Naḥman says:
He was a KOFER.
It is written here: “And they like men [adam] have transgressed the covenant,” and it is written there: “He has broken My covenant,” and it is written in a third verse: “And then they shall answer: Because they have forsaken the covenant of the Lord their God and worshipped other gods and served them” (Jeremiah 22:9).
