Genesis 8:15-9:7
Genesis 8:15-9:7 is the canonical first iteration of three load-bearing institutions and the verbal completion of a prophecy issued five generations earlier. Noah builds the first mizbeach, offers the first olah, and YHWH smells the first reach nichoach — and the aroma's Hebrew root (n-w-ch) is Noah's own name. The post-Flood charter then renews the Adamic mandate verbatim and grounds the lex talionis in tselem Elohim, an image whose LXX rendering eikōn lands at Col 1:15 on Christ.
Genesis 4:1–26
Genesis 4 is the fall enacted. Cain inherits Adam's vocation, is warned in the exact construction Eve was warned with, exiled eastward as Adam was exiled, and fails the shamar charge by killing the brother he was meant to keep. Yet within the same chapter the seed-line continues: Eve names Seth zera acher — another seed — and men begin to call on the name of Yahweh.
