In Genesis, Noah was told to place animals on the Ark with his family to preserve life.
Genesis describes Noah bringing representatives of land animals and birds aboard the vessel. The passage uses different instructions for animals considered clean and unclean: seven pairs of clean animals and one pair of animals not classified as clean. The wording is therefore more detailed than the popular phrase “two of every kind.”
The text’s purpose is preservation. After the Flood, the animals can reproduce and repopulate the Earth. The account also mentions food for Noah’s household and the animals, showing that the Ark is presented as a temporary living space rather than merely an empty boat.
The animal categories are ancient biblical classifications, not a modern biological taxonomy. Consequently, the story should not be read as providing a modern species count. Its central point is the survival of animal life through the catastrophe.
