Bereishit 5:1-2 of Parashat Lech Lecha
Zeh sefer toledot Adam be-yom bero Elokim adam bi-demut Elokim asah oto zachar u-nekevah bera'am va-yevarech otam vay-yikra shemam Adam be-yom hi-baram.
5:1-2 This is the book of the generations of Adam.  In the day that G-d created man, in the likeness of G-d made He him; male and female created He them, and blessed them, and called their name Adam, in the day when they were created.
HiBaRAM (they were created) - Adam and Chavah, the progenitors of the human race - for the sake of those very letters in Hibaram.  Rearrange them and you find the name AVRaHaM, Abraham.
