In Genesis’s Noah’s Ark story, Noah was told to take seven pairs of clean animals aboard.
Genesis 7:2 distinguishes clean animals from animals that are not clean. Noah is instructed to take seven pairs of clean animals, male and female, while taking one pair of animals that are not clean. Birds are also described separately with seven pairs of each kind.
This detail is often simplified into the phrase “two of every animal,” but that summary does not capture the distinction made in Genesis. The account contains both a general pairing instruction and a more specific instruction that gives clean animals a larger representation.
The reason becomes clearer after the Flood: Genesis later describes Noah offering burnt offerings from clean animals and clean birds. The extra animals therefore matter within the story’s ritual context. The passage is also part of a well-known chronological and textual discussion about the Flood narrative’s differing animal counts.
