In Genesis, God tells Noah to make rooms in the Ark to divide its interior.
The construction instructions in Genesis 6 describe an Ark with internal compartments. English translations commonly render the relevant word as “rooms,” though some translations use terms such as “compartments” or “cells.” The instruction appears alongside the commands to build the Ark, cover it with pitch, and give it a roof, door, and levels.
These rooms are not the same as the Ark’s window or door. Genesis separately mentions a door in the side and an opening or window associated with the upper part of the structure. The rooms describe the internal arrangement needed for the people, animals, and supplies in the story.
The passage does not provide a detailed floor plan or name a precise number of compartments. Therefore, “rooms” is the concise canonical answer rather than a modern architectural reconstruction.
