samhachaim:
1. Rivka and Tamar
2. Noach sent the raven/dove out of the window. Avimelech saw Yitzchak “m’tzachek et ishto” through the window. The two women in Nach who looked out the window are the mother of Sisra, and Michal, the daughter of Shaul
3. The story of the Nachash and Adam and Chava
The story of the N’chasim that were sent after B’nei Yisrael complained about water and food. Moshe made a Nachash N’choshet (B’midbar 21:5-10).
Moshe describes to B’nei Yisrael how Hashem led them through the midbar filled with snakes (D’varim 8:15)
Dan, in Birkat Yaakov is described as a “nachash” (B’reishit 49:17)
And then of course “Nachash” in its other meaning (divination) is used many times in Torah (for instance ini Bircat Bil’am (B’midbar 23:23) and the general prohibitions against “nachash”, “kosem”, etc )
Now if you want to go into Nach, there was a King of Ammon named “Nachash”…
