You must make a clear distinction (difference) between things that are holy and things that are not holy. You must make a clear distinction between things that are clean [118] and things that are unclean. [119]
Those teachings are so people can know unclean [145] animals from clean [146] animals. So people will know which animals they can eat and which animals they must not eat.
The Pharisees and teachers of the law saw that some of Jesus’ followers ate food with hands that were not clean. (“Not clean” means that they did not wash their hands \{in the way the Pharisees said people must\}.)
I am in the Lord Jesus. And I know that there is no food that is wrong to eat. But if a person believes that something is wrong, then that thing is wrong for him.
The husband who is not a believer is made holy through his \{believing\} wife. And the wife who is not a believer is made holy through her \{believing\} husband. If this were not true, then your children would not be clean. But now your children are holy.
