Isaiah 54 gives the clearest later inspired reuse. God explicitly invokes “the waters of Noah” and compares His sworn promise after the Flood with His assurance of steadfast mercy toward Zion. This is a genuine canonical connection because Isaiah himself reaches back to Noah’s covenant.

The Noahic covenant should also be distinguished from the new covenant. Hebrews 8’s “better covenant” is discussing the new covenant in relation to the Mosaic covenant, not saying that Jesus fulfills or replaces the covenant with Noah. All of these covenants belong to one biblical story, but they have different parties, promises, signs, and functions. The covenants should be traced as developing within one biblical story without flattening them into one thing.

Revelation 4 pictures a rainbow around God’s throne, which naturally recalls covenant and judgment imagery, but Revelation does not identify that rainbow as a direct reference to Genesis 9; Ezekiel’s throne vision is the closer textual background. The Genesis-Revelation association is therefore a meaningful echo, not an explicit fulfillment.

The integrated story is: Flood judgment → creation preserved → Noahic covenant → Isaiah reuses Noah’s sworn promise as a model of steadfast mercy → later covenants advance God’s redemptive purposes → final Scripture still presents the covenant-keeping God enthroned over creation. The covenant with Noah remains what Genesis says it is: God’s enduring commitment concerning the earth and all flesh.

Presence / covenant lens: The Noahic covenant is not merely an early version of every later covenant. Genesis gives it a universal creation-preserving scope—Noah, his descendants, and every living creature—with the bow as its sign. Later covenants add different promises, signs, parties, and redemptive functions.
