Isaiah 26:20 → Genesis 7:16

Isaiah calls the remnant to a sheltering-through-wrath that unmistakably echoes the ark: "Go, my people, enter your rooms and shut your doors behind you. Hide yourselves a little while until the wrath has passed" (Isaiah 26:20). The Genesis pattern supplies the shape — "And they entered… as God had commanded Noah. Then the LORD shut him in" (Genesis 7:16), where God Himself seals the righteous remnant inside the ark while the flood of judgment falls outside. Both texts hold the same theology in a single image: a divinely secured enclosure, an appointed people brought inside, wrath poured out beyond the door, and a "little while" of hiddenness until indignation is spent. Isaiah reapplies the ark-event as a prophetic summons — the remnant is to hide in God as Noah hid in the ark — and the pattern runs forward to its consummation in Christ, in whom believers are hidden through the judgment He bore (cf. Col 3:3; 1 Pet 3:20-21). The correspondence is thematic-verbal (enter / shut / until the wrath passes), held as an analogy within the salvation-through-judgment trajectory rather than pressed as a designed type.
