In Genesis, Noah opened a window in the Ark after the waters receded.
Genesis 8:6 says that after forty days Noah opened the window he had made in the ark. He then sent out a raven, followed by a dove, to learn whether the floodwaters had subsided from the earth. The window is therefore part of the narrative’s sequence for observing conditions outside the vessel.
The text distinguishes this window from the ark’s door, which Genesis mentions earlier as being in the side. It also does not call the opening a chimney, hatch, or skylight door. Some translations use “window,” while related ancient wording can lead to slightly different renderings, but window is the standard English answer.
The raven and dove episodes are separate tests within the same chapter. The dove’s later return with an olive leaf is often remembered more vividly, but the first opening Noah made after the specified period was the window.
