'This one will comfort us' (5:29) — righteous, blameless in his generation, walked with God (6:9). Built the ark, offered the first altar's sacrifice (8:20), received the first covenant (9:9-17), planted the first vineyard and fell (9:20-21). Died at 950 (9:29). His name's rest-root (n-ch) puns through the whole flood story.
