Matthew 7: 6 says, "Don't give the holy things to dogs, and don't throw your precious ball in front of pigs, lest they trample on pearls and turn around and bite you." What do you mean?

This section teaches believers to be smart in the world (too 10: 16) and not to introduce precious things to others casually, lest others spoil themselves and invite others to attack them. It can be seen that the Lord doesn't want us to be Christians who can't tell right from wrong, but should know who is a pig and who is a dog.

A "sacred object" refers to something dedicated to God.

"Pearl" refers to precious cosmetics.

"Dog" and "pig" both refer to unclean people (1 pet. 2. 2: 22).
