Commentaries:
The clean and unclean laws are specifically mentioned early in God's Word, in the account of the Noachian Flood, when Noah was commanded to take "seven each of every clean animal" (Genesis 7:2). When he and his family were back on dry land, Noah "took of every clean animal and of every clean bird, and offered burnt offerings on the altar" (Genesis 8:20). This suggests that these laws were known and practiced before the Flood'even from the earliest days of mankind (compare Genesis 4:4, Abel's acceptable offering). Since there were no Jews or Israelites then-not even any Hebrews-these laws are obviously for all humankind.
