Genesis instructs Noah to make a window for the Ark. Genesis 6:16 includes the instruction alongside the command to finish the vessel and place its entrance in the side.
The Hebrew wording behind this feature has generated translation and interpretation questions. English Bibles commonly render it as “window,” although translations differ in how they describe its precise form or placement.
The window becomes important later in the narrative. After the waters have covered the earth, Noah opens the Ark’s window and sends out the raven and then the dove to discover whether the land has dried.
The window is therefore both a construction detail and a narrative device. It provides the opening through which Noah observes conditions outside and releases birds. It is different from the Ark’s door, which Genesis separately identifies as being in the side of the vessel.
