According to Genesis, Noah brought seven pairs of clean animals into the Ark.
Genesis 7:2 tells Noah to take seven pairs—male and female—of clean animals, while one pair of each kind of unclean animal is specified. The clean animals were also available for food and for sacrifice after the Flood, which explains why the narrative distinguishes them from unclean animals.
Translations sometimes render the Hebrew instruction as “seven” of each clean animal rather than “seven pairs.” This wording difference creates a well-known counting issue: readers may see seven animals, seven pairs, or seven male-and-female sets depending on the translation. “Seven pairs” follows the common traditional English interpretation.
The passage also distinguishes birds, assigning seven pairs of birds in the same instruction. This detail differs from the simplified image that every species entered the Ark in exactly one pair.
