Exodus Exodus 40:1-38
The book of Exodus ends by giving God a home: the finished tabernacle is raised, sealed with the obedience-refrain, and then the cloud covers it and the glory of the LORD fills it — the goal the mountain itself could not hold, and the same rare formula that will one day fill the whole earth.
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.
