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 7:1-8:14
Eighty-three Hebrew verses chiastically center on a single sentence: va-yizkor Elohim et-Noach (Gen 8:1). The Flood narrative is the canonical first iteration of uncreation-and-recreation — Gen 1's cosmogonic lexicon returns inverted, the judgment-execution verbs run forward into the Red Sea at 34% coverage, and the dove-over-water of Gen 8:8-11 becomes the only canonical pair with Jesus' baptism that 1 Pet 3:21 names as antitype.
Genesis 6:9-22
The toledot of Noah opens with the first canonical tsaddiq, runs through the only OT verse where atonement-noun and atonement-verb co-occur, makes the first canonical covenant, and closes with a sentence that recurs nearly word-for-word when Moses finishes the tabernacle. The Hebrew lexicon discloses Noah's ark as the canonical first iteration of the covenant-sanctuary-atonement cycle the rest of the Old Testament builds out.
