Genesis 12:10-13:18
A heavy famine drives Abram down; a heavy wealth carries him back up. Between the two, Yahweh strikes Pharaoh with great plagues — the first plague-word in the canon. Then Lot lifts his eyes and chooses the plain that is about to burn, and Yahweh tells Abram to lift his eyes and see the land he will give to his seed forever. Gen 12:10–13:18 is the miniature Exodus that frames the covenant's first 'forever.'
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.
