What does the Bible say about clean and unclean animals in Genesis?

In Genesis 7:2, God instructs Noah to bring clean animals into the ark by sevens, while unclean animals are to be brought by pairs. This distinction is significant because it reflects God's holiness and the requirements of the Law that would later be given to Israel. Clean animals were those that could be sacrificed and consumed, symbolizing God's provision for His people. Furthermore, the distinction emphasizes the need for God to make a difference between the holy and the unholy, as outlined in the Law and ultimately fulfilled in Jesus Christ, who purifies and sanctifies His people.
