To people who are pure, everything is pure. But to those who are full of sin and don’t believe, nothing is pure. Really, their thinking has become evil and their consciences have been ruined.
If any part of a dead, unclean animal falls on something, that thing is unclean. It may be a clay oven or a clay baking pan. It must be broken into pieces. These things will remain unclean. They will always be unclean for you.
