Genesis 17:1-14
After thirteen years of silence following Ishmael, Yahweh appears to Abram at ninety-nine and names himself by a name the older Greek witness will quietly suppress. He commands the walk that Noah walked, gives the sign that the rainbow gave, and inscribes the covenant into flesh. Gen 17 is where the canon places its closed set of two: the bow in the cloud and the cut in the body — the only two covenant-signs Scripture designates with the precise formula ot berit. The article reports what the text says before tracing how heart-circumcision and the eighth day carry the chapter forward across six centuries to Paul.
Genesis 15:1-21
Abram falls into a deep sleep while a smoking firepot and a flaming torch pass alone between the halved animals. The covenant is cut without his participation. One verse later, Yahweh reckons his faith as righteousness — a half-verse Paul will quote four times in Romans 4 alone. Gen 15 is the locus of the unilateral covenant, the chapter where God himself walks under the self-curse, and the OT verse from which the New Testament builds its entire grammar of grace.
