Gênesis 6:16

16 Make a roof for it, leaving below the roof an opening one cubit That is, about 18 inches or about 45 centimeters high all around. The meaning of the Hebrew for this clause is uncertain. Put a door in the side of the ark and make lower, middle and upper decks.

16 Huma janella farás na arca, e hum covado da banda de riba a acabarás, e a porta da arca porás a sua ilharga; e farás-lhe sobrados baixos, segundos, e terceiros.
