According to Genesis, how many animals of each clean kind enter Noah’s Ark?

According to Genesis, seven pairs of every clean animal enter Noah’s Ark.

Genesis 7:2 instructs Noah to take seven pairs of clean animals, male and female, while taking one pair of animals that are not clean. Genesis 7:3 gives a parallel instruction for birds, saying seven pairs are to be taken so their kind can be preserved across the earth.

A frequent simplification says that the Ark carried only two of every animal. That wording reflects the one-pair instruction for unclean animals and the broad summary in Genesis 6:19–20, but the more detailed instructions in Genesis 7 distinguish clean from unclean animals.

The clean-animal distinction is connected with later Israelite dietary and sacrificial categories. Genesis does not provide a modern biological species list, so “kind” is a textual category rather than a precise equivalent of today’s species classification.
