Genesis 6:16

The Flood

You are to make a roof for the ark, finish its walls a cubit from the top, place a door in the side of the ark, and build lower, middle, and upper decks. Genesis 6:16 · Berean Standard Bible

What It Means

Genesis 6:16, in plain English

The ark needs a roof, walls that go up to a cubit below the top, a door on the side, and three levels inside—upper, middle, and lower decks.

Why it's here

We're getting the blueprint now. The roof would protect the contents from rain. The walls leave a cubit of space below the top, which some scholars think might relate to ventilation or light. The door gives entry and exit. The three decks provide space to organize all the animals and provisions. These are the practical details of a seaworthy vessel designed to preserve life.

Who's speaking

God, completing the structural specifications

Where it sits in the story

Each detail reflects God's intention to preserve life through the judgment. He's not just saving Noah arbitrarily—He's meticulously designing a vessel that will protect everything needed to start humanity over.

A Closer Look

The scholar's commentary

God prescribes the ark's internal structure: a roof, walls (finished to a cubit below the top), a side door, and three decks for organization and circulation.

Language and setting

The term צֹהַר (tsohar, often rendered 'window' or 'roof') likely denotes the uppermost opening—possibly a continuous skylight or cupola running the roof's length. The phrase 'a cubit from the top' (בְאַמָּה מִלְמָעְלָה, be-amah mil-ma'lah) suggests either that walls rise to within a cubit of the roof peak or that an opening exists one cubit below the top—necessary for ventilation and light. The 'door in the side' provides singular entry point, emphasizing God's controlled access—only the righteous enter; all others remain outside. The three decks (קוֹמוֹת, qomot, 'stories') correspond to Noah's three sons, suggesting genealogical organization of space. Philo allegorized these levels as virtue, temperance, and piety.

Voice

God (Elohim), continuing structural specifications

Significance

The ark's carefully designed interior organization reflects divine order imposed upon chaos—God's purposeful construction contrasts with antediluvian disorder, prefiguring the orderly cosmos that will emerge after judgment.

In context

Genesis 6:14–18

14Make for yourself an ark of gopher wood; make rooms in the ark and coat it with pitch inside and out.

15And this is how you are to build it: The ark is to be 300 cubits long, 50 cubits wide, and 30 cubits high.

16You are to make a roof for the ark, finish its walls a cubit from the top, place a door in the side of the ark, and build lower, middle, and upper decks.

17And behold, I will bring floodwaters upon the earth to destroy every creature under the heavens that has the breath of life. Everything on the earth will perish.

18But I will establish My covenant with you, and you will enter the ark—you and your sons and your wife and your sons’ wives with you.
