what does the bible say?
Genesis specifies that Noah took seven pairs of clean animals and two of every unclean animal onto the ark. Clean animals were named this way because they were suitable for sacrifice and eating. Leviticus and Deuteronomy further detail the classifications of clean and unclean. The number of animals on the ark highlights God's purposeful plan for biodiversity and restoration after the flood and His care in creating an ark big enough to support that. This demonstrated His care and commitment to preserving creation. We, as believers, are called to steward and appreciate the natural world He created.
